There is a user on Youtube by the name of Jensaarai1 who has posted a couple different Star Wars matches. I thought I’d give my thoughts on them and see what people think.
Darth Vader Vs. Qui-Gon Jinn
Vader should win this just as soundly as Darth Maul did, if not moreso. First off, Vader is at worst as good a lightsaber duelist as Darth Maul but is actually probably better, given that he fought evenly with an amped up version of Darth Maul, fought evenly with RotJ Luke, who is comparable to both Mace Windu and Count Dooku, and also fought evenly with a version of Obi-Wan comparable to the one Darth Maul fought evenly with. But even if he’s Maul’s equal, that still makes Vader more than capable of besting Qui-Gon in a saber duel for obvious reasons. In terms of the Force there is no contest. Vader has uprooted trees and destroyed cathedrals. Qui-Gon never accomplished anything to that effect with the Force. Strength also goes to Vader, who has supported the weight of a dozen stormtroopers. Once again, Qui-Gon has done nothing to compare and even worse is prone to fatigue as of TPM, which would work against him. In terms of speed however, the two are even. Qui-Gon's physical power was sufficient to repeatedly run invisibly fast, fight fast enough to form shields out of his lightsaber blade, deflect torrents of blaster fire, and strike with enough force to stagger Maul. Vader meanwhile has moved faster than thought, produced afterimages from the movements of his lightsaber, and like Qui-Gon has formed shields out of the movements of his blade and deflected torrents of blaster fire.
So in all, while the two are comparable in speed, Vader outclasses Qui-Gon in strength, force ability, and saber dueling. Really I see Vader only having a ton of trouble here in a straight-up saber duel and even there he wins. If Vader makes good use of his Force ability the fight ends all the more quickly, though I wouldn’t quite say its a stomp given how Vader usually struggles with his opponents even when he wins.
Darth Tyranus Vs. Darth Maul
People almost invariably say that Tyranus/Dooku wins, and looking at the evidence its true. In terms of saber skill, Maul is marginally below Mace Windu by virtue of being equal to a version of Obi-Wan who is marginally below Mace Windu and killing someone who once stalemated Mace Windu. Dooku meanwhile has stalemated Mace in the past and the two have also beaten each other before, showing that they are equals. Dooku has also beaten both General Grievous and Sora Bulq, two lightsaber duelists with comparable skills to Maul (both have stalemated Mace Windu twice each).
In terms of the Force, Tyranus is at least as powerful as the Clone Wars iteration of Darth Maul (the TPM version of Maul lacks Force feats) but is likely even more powerful. Tyranus collapsed a ceiling, Maul collapsed a small cave. Tyranus used Force Choke to kill Weequay Pirates, and while Maul has yet to use Force Choke to kill anyone, his usage of it on Satine, Bo-Katan, and others shows that he would have been more than capable of doing so if he desired. He has also force-choked Obi-Wan, something Tyranus has also accomplished. But while their telekinesis and force choke are comparable to even, Tyranus has something Maul does not: Force Lightning. While Tyranus is not among the most powerful practitioners of Force Lightning, his usage of the ability is still solid, as he has used it to beat Anakin Skywalker and Asajj Ventress among others.
Strength does pass to Maul, and this might give him the edge in a saber duel, but it is unlikely that this would be enough to guarantee Maul an outright victory, especially since General Grievous has also demonstrated better strength feats than Dooku and yet he has still lost to him. In the end, Tyranus does indeed win, though the fight itself is a lot closer than some people might think.
Yoda Vs. Darth Plagueis
This is a close one. Plagueis has demonstrated some truly incredible force feats, not the least of which would be force lightning capable of turning people to dust. Yoda struggled to hold off Palpatine’s lightning and in one instance failed to stop it, and while Plaugueis’ lightning isn’t quite as powerful, its not too far below based on what has been shown, as Palpatine too has used lightning to turn people to dust. Yoda for his part has demonstrated decent telekinesis feats, namely redirecting a senate pod tossed at him by Sidious, stopping and moving a collapsing pillar, and (my personal favorite) lifting up an army of droideaks.
Speed-wise Plagueis has run so fast that his lightsaber appeared as a blur, and also fought off an army of Kursid Warriors without being touched. Yoda however, was able to fight Palpatine as a perfect equal, whose speed feats transcend those demonstrated by Plagueis at best and equal them at worst. So Yoda can keep up here. Strength-wise, Yoda is deceptively strong, among other things having bested Depa Billaba, Saesee Tiin, and Ki-Adi-Mundi simultaneously without any weapons. Plagueis to compare has kicked armored individuals so hard their torsos went flying. Those three Jedi Masters Yoda bested are certainly more impressive than generic non-Force Sensitives, but Plagueis’ strength feats are still noteworthy.
In terms of saber dueling this is where Yoda shines. He has Plagueis completely outclassed in this arena. Plagueis has never beaten a notable lightaber duelist, merely sparred with a version of Palpatine who had not yet displayed any feats and beaten Darth Venamis, who is as featless as they come in terms of saber dueling and is only impressive in terms of speed. Yoda meanwhile has fought a vastly superior version of Palpatine as a perfect equal, beaten/overwhelmed Dooku multiple times, beaten Mace Windu, beaten those three aforementioned Jedi Masters, two of whom are only marginally below Mace in saber dueling, etc. There is no comparison between the two whatsoever here.
In all while Plagueis can easily match and possibly surpass Yoda in the Force department, and the two are comparable in strength and speed, Yoda’s vastly superior dueling skills and the fact that he’s at least approachable to Plagueis in the Force and raw strength both give him the edge needed to win in my opinion.
Darth Vader Vs. Exar Kun
The thing with Exar Kun is that he is one of those Star Wars characters who should be way better than he is. But alas, his feats just don’t reflect his lofty reputation and as such Vader wins handily against him.
In terms of lightsabers, the disparity between the two is not as great as it is in other arenas. Exar Kun killed Vodo-Siossk Baas, who was good only by reputation. Vader killed The Dark Woman and Roan Shyre, both of whom were only good by reputation. So there’s no real disparity there. Where Exar Kun has stalemated Ulic Qel-Droma, Vader has stalemated an amped TPM Darth Maul, a version of Obi-Wan that is technically inferior to his RotS incarnation but still capable, and a version of Luke comparable to Mace Windu and Darth Tyranus that would go on to stalemate Flint while holding back and hold his own against Lumiya while holding back (and being unfamiliar with her Light Whip weapon). This is what tips the scale in Vader’s favor and makes him Kun’s superior in terms of dueling. But Exar can at least give Vader a fight here.
Regarding the Force though, its not even a contest. As has already been stated, Darth Vader has uprooted trees and destroyed cathedrals, not to mention he has utilized other Force Powers as well such as Force Scream, Dun Moch, Alter Environment, and of course Force Choke. Exar Kun meanwhile, has only manifested Force Drain within the confines of his Temples which radiate with a dark side aura that bolsters his powers, rendering it ineffective in a duel on neutral ground. Exar Kun’s Force Blast when not amped by his temple’s energies was unable to kill Aleema Keto (a featless being), and he has shown no proficiency in either Dun Moch or Alter Environment, and his Force Lightning is sub-par. What makes Exar Kun’s mediocre Force showings here especially pathetic is the fact that all of them were done when wearing a Sith Amulet that supposedly boosted his Force ability. When the above was all he could accomplish with it, that’s pretty damning ability wise. Vader wins a Force fight in a stomp or near-stomp.
The advantage in both Strength and Durability goes squarely to Vader. Kun has few if any showings in either arena, whereas Vader has dented bulkheads, supported the weight of a dozen stormtroopers, and continued fighting after losing an arm and suffering other injuries. I'd even argue Vader is better in terms of agility considering he was able to make his way through a ruined Star Destroyer floating in space. Really Exar Kun is pretty badly outmatched. While a lightsaber duel will at least be a solid fight, in an all-out fight or force fight Vader wins with much less trouble.
Obi-Wan Kenobi Vs. Vodo-Siossk Baas
This is the kind of mismatch that is pitting one of the best lightsaber duelists the Jedi Order ever produced against a featless (or near featless) individual. To sum it up: Vodo-Siossk Baas lost to Exar Kun and has no other dueling showings outside of this. Not a one. Obi-Wan meanwhile has beaten/stalemated Asajj Ventress, beaten Savage Opress, and stalemated Darth Maul. He also has Force feats, which Vodo is lacking in. So in the end Obi-Wan beats him just as easily as Exar Kun did, it not moreso.
Kit Fisto Vs. Ulic Qel-Droma
For Kit Vs. Ulic, while Kit Fisto’s lightsaber form Shii-Cho is less useful against a single individual with a single lightsaber, his objective showings (such as doing well against General Grievous and also elite Mangaguards, ones that gave Obi-Wan a challenge) are still such that he is more than capable of holding his own. Qel-Droma's main claim to fame is stalemating Exar Kun, which is pretty good, but not enough on it's own considering Kit would beat Kun more often than not (Shii-Cho advantage among other things). And as with Obi-Wan Vs. Vodo-Siossk Baas, Kit Fisto has decent Force showings that Qel-Droma is lacking in. Even granting that Kit's best Force showings are probably not something he could do on dry land, he has still (alongside Plo Koon) shielded him and his men from an avalanche caused by Asajj Ventress and also moved large machinery with his TK. The one thing I will say to this effect though is that it doesn't seem to be Kit's style to rely heavily on Force attacks, and thus it may not make much of a difference in the end anyway. One thing that might make a difference though is speed, Kit's being such that it astounded Obi-Wan, who has speed showings of his own (such as running in a blur). In all, I think this is a closer, better fight than the above one, but as of right now I think I'll favor Kit Fisto for a majority.
Darth Tyranus Vs. Darth Malgus
While this is not as much of a mismatch as I initially thought it to be, Tyranus still wins a solid majority against Malgus. For starters he destroys Malgus in a saber duel. While Malgus is objectively stronger than Tyranus, so is Anakin, and that didn’t stop him from losing to the Count on Geonosis. Tyranus’ actual dueling feats are also objectively better. Beating the likes of Obi-Wan, General Grievous, and in one case Mace Windu, far exceed beating Kao Cen Darach, Ven Zallow, and Padawan Satele Shan, not to mention losing to the Emperor’s Wrath and Kallig (or alternatively the Hero of Tython and Barsen’thor).
In terms of the Force the two are more comparable, but there is still a clear gap in Dooku’s favor. Malgus’ Force Lightning took down three Jedi Masters who had their lightsabers up, but Dooku’s took down Asajj Ventress backed up by two Nightsisters, all three of whom had lightsabers. There’s no great disparity there. Force telekinesis though Malgus never showed much, certainly not enough to match Tyranus’ collapsing a ceiling or causing a large metal pillar to fall. So while the two are at least comparable in the Force, Dooku is still the superior here, and coupled with his being a vastly superior lightsaber duelist ensures that he wins handily against Malgus. As has already been stated, the only realm Malgus surpasses Dooku in is in strength, and this by itself is not enough to get him a win.
Kit Fisto vs. Darth Maul
With this one it depends largely on which version of Maul we’re talking about. TPM Darth Maul is lacking in Force feats, whereas CW Darth Maul has collapsed a tunnel and made liberal use of Force Choke. Kit Fisto’s best Force feats were mostly accomplished when underwater and thus may not be applicable to a fight on dry land. Having said that, the two are still comparable in the Force arena if we use CW Maul. It not, Kit comfortably surpasses him in this arena.
Speed-wise, Kit has run in a blur, deflected blaster bolts, shaped fans out of his lightsaber blows, and moved fast enough to astound Obi-Wan with his speed. Maul, to compare has disappeared in a blur, sprints five times faster than a human being can run, and travels by leaping distances so quickly that footage from recording devices would have to be slowed down to display him.
But where the two are comparable in both speed and the force, strength passes soundly to Maul, who has broken durasteel binders and thrown spydrs, among other showings. In terms of dueling, the two are comparable. Kit was overwhelming Grievous and also fought Ventress, and Maul is only a marginally better duelist then them if at all. Also of note is that Shii-Cho is useful against multiple blades and multiple opponents both, though the latter is not present and Maul can circumvent the former by simply not having both of his lightsaber blades ignited, though it might take him a few moments to realize that his opponent’s style is Shii-Cho, which could give Kit all the time he needs.
In the end I say Kit beats TPM Maul more often than not due to 1: Shii-Cho (even though again, Maul can circumvent this obstacle) and 2: having Force feats that Maul is lacking in. CW Maul however beats Kit more often than not due to having superior strength feats and being able to match Kit in every other arena. Not to mention that CW Maul's dueling feats are also arguably better than Kits.
Darth Vader Vs. Yoda
Even moreso than some of the TotJ Characters Vs. RoE Characters fights this is to put it simply, silly. Because I’m too lazy to elaborate on this one, and honestly I think most people are intelligent enough to guess why this is one-sided on their own, I’ll just have a bit of irrefutable ABC logic and be done with it: Vader knew he was not strong enough to beat Palpatine by himself and therefore never bothered to challenge him alone. Yoda fought Palpatine as an equal in saber dueling and though he still lost to him at least put up a fight. With this in mind, who do you think wins?
Darth Malgus Vs. Sora Bulq
Changed my verdict with this one. While Sora has fought evenly with Mace Windu, who is a far better lightsaber duelist than Ven Zallow and Kao Cen Darach, the reason for this was Sora's knowing the fighting style Mace uses very well because it was his own. Outside of that fight, Sora has beaten Quinlan Vos, was beating Quinlan Vos when he was in a Force-Rage, and only lost due to assuming him defeated and lowering his guard, which allowed Vos to kill him, and beat Master Tholme. So in all, I see little disparity in skill here. Malgus does have better strength and force feats though, which should probably be the scale-tipper he needs to win. His pain tolerance is also substantial, though I would actually argue that won't mean as much in the end, since lightsabers tend to do their job as far as putting people down goes. Still, with comparable dueling skill and superior strength and force ability Malgus can probably win this.
Qui-Gon Jinn Vs. Asajj Ventress
Ventress should win this almost as soundly as Darth Maul did, if not just as soundly. Ventress is pretty comparable to Maul in saber dueling, and if either one is better than the other, its not by a wide margin, assuming we’re using Ventress later in the Clone Wars that is. The version of Ventress that lost to Dooku, Padawan Anakin, and General Grievous in that order loses to Qui-Gon, but even this iteration of the character still puts up a fight. But the Ventress who has consistently given mid to late CW Obi-Wan and Anakin trouble and was only barely bested by Mace Windu wins handily.
Regarding the Force, Ventress has Qui-Gon beat here no matter which version it is, as Qui-Gon has never done anything close to collapsing a ceiling or causing an avalanche. That said, Ventress rarely uses the Force to any substantial degree in fights, as its not in her character. Its still noteworthy though, as in the event that Force Powers do enter the equation, Qui-Gon is outclassed. So really between that and superior dueling ability, Ventress’ fight with Qui-Gon ends the same way his fight with Darth Maul did unless its Ventress at the very beginning of the Clone Wars, who loses to Qui-Gon after a fierce duel.
Qui-Gon Jinn Vs. Sora Bulq
Another close fight for Sora. Granted, both have stalemated Mace Windu before, but the time at which Qui-Gon did this is ambiguous and it is likely that Mace was not yet in his prime. Bulq conversely has fought evenly with Mace Windu both before and during the Clone Wars and in the second duel while Mace did beat him it was by using the Force, not by virtue of being more skilled (though Mace is in fact more skilled, just not by a large margin). Outside of this, Sora's feats are decent, but Qui-Gon's got showings to rival them (beating the Dark Jedi Xanatos and giving TPM Maul a fight namely). So they're probably pretty close in respects to dueling skill. As of now I'm seeing little if any disparity.
Neither opponent has any force feats of note that I know of, but Qui-Gon does have some pretty good speed feats. Now the one thing to note is that Qui-Gon is quite prone to fatigue as of TPM, but this is largely due to the physically demanding nature of the form Qui-Gon specializes in, namely Ataru. Nowhere does it say that Qui-Gon's skills decreased at all. Nevertheless, lower stamina could conceivably cost him in a duel against an opponent who is roughly his equal as a duelist. Ultimately, I'd say this could go either way. If either one is better than the other in dueling, it's not by that large a margin. Qui-Gon seems to surpass Sora in speed but fails in terms of stamina. So in all, a pretty even match-up. Not sure who wins this one.
Darth Malgus Vs. Darth Vader
Despite Malgus being in many respects a shameless nod to Vader and seemingly being a lot more flashy, in the end Vader outclasses Malgus in literally every single arena. In dueling, Malgus has not ever defeated terribly noteworthy opponents. Vader for his part has again, stalemated his son as of RotJ, Obi-Wan as of ANH, and an amped TPM Darth Maul, all of whom surpass Kao Cen Darach, Ven Zallow, and a featless iteration of Satele Shan (and frankly probably Grandmaster Satele too if we're only talking about lightsaber skill). In the Force Malgus has never accomplished anything on the level of Vader's uprooting trees, destroying walkways, throwing massive droids around, and destroying a cathedral. Many of Malgus' best feats, such as breaking a person's bones with Force Push and using Force Choke to kill someone have either been replicated by Vader (Choke) or just straight up exceeded.
Strength, speed, and even knowledge all also pass to Vader. Malgus' strength is decent, but Vader has supported the weight of a dozen stormtroopers, a feat Malgus has never surpassed or replicated. In terms of speed Vader has moved faster than thought, produced afterimages from the movements of his lightsaber, and has formed shields out of the movements of his blade and deflected torrents of blaster fire. Malgus has replicated some of these feats, so this is one arena where Malgus is more approachable to Vader, but all this means is that Vader will not blitz Malgus. But when Vader's demonstrated TK and dueling are both superior there will be little Malgus can do to challenge him. Furthermore, Vader has demonstrated numerous Force powers that Malgus to my knowledge has never displayed, such as Dun Moch, Alter Environment, and others. Malgus has not even displayed Force Deflection, which Vader has frequently employed.
Honestly aside from speed the only arena Malgus is approachable to Vader in is durability. Vader has continued to keep fighting even after losing limbs and has withstood assault from all manner of heavy weaponry. Malgus to compare survived a close-range grande blast followed by a massive force push (though this was able to put him down and he needed to have a breather mask akin to Vader's own afterwards). So honestly Vader likely surpasses him here too.
So in the end Vader wins this one handily, though not quite effortlessly. Malgus is decent enough, but he simply cannot compare to Vader where it counts.
Vodo-Siossk Baas Vs. Darth Plagueis
Not even close. I've already listed Plagueis' feats above. Vodo-Siossk Baas is literally feat-less. This is a horrific mismatch. Moving on.
Darth Zannah Vs. Shaak Ti
While both are largely pathetic lightsaber duelists, Zannah has demonstrably better Force power. And while her telepathy will not be able to effortlessly overwhelm Shaak Ti due to the fact that like most Jedi Shaak Ti has some TP resistance, I would not put it past Zannah's Sith Sorcery to be able to overwhelm Shaak in the end.
Saber-wise the two are equally abysmal. Neither Zannah nor Shaak Ti has ever defeated a noteworthy lightsaber duelist (and no, Galen Marek, who Shaak was overwhelming in their duel is not noteworthy, quite the opposite). The only half-decent feat of Zannah's is stalemating a bloodlusted Darth Bane twice and for Shaak Ti soloing an army of Magnaguards, whose skill levels are so inconsistent it's kind of ridiculous. Honestly, between that and Zannah's using the defensive style Soresu, I'd actually favor Zannah in a duel, but not by a large margin.
So in the end, between slightly superior saber skill and her Sith Sorcery (considered by Darth Plagueis to be some of the best there ever was) I see Zannah ultimately prevailing. Shaak Ti, cool as she is is simply not among the better duelists or Force users of the RoE Jedi Order.
Kit Fisto Vs. Obi-Wan Kenobi
This is a very close one, in fact I'd say it's the closest fight out of all of these. Dueling-wise, the two have both done well against Grievous, though in both cases they had their specific lightsaber forms (Shii-Cho and Soresu respectively) giving them an edge (in fact, Obi-Wan was sent after Grievous precisely because his Soresu would be a good counter to GG’s insane attacks).
Outside of that, the two have also both fought Ventress before. But whereas Kit has never defeated Ventress to my knowledge, Obi-Wan has beaten her, though at the same time he has also lost to her before, and stalemated her other times, which basically means they’re about even. Kit for his part lost to Ventress, but his Shii-Cho is ill-suited to Makashki, which did give Ventress an edge that she would not have had against Obi-Wan. Ultimately, looking at their saber skills, I’d say there’s little if any disparity to be had, though since Kit’s form is less useful against a single opponent with a single lightsaber blade, he is at a bit of a disadvantage, and therefore I might favor Obi-Wan in terms of who is the superior duelist.
In terms of the Force, Obi-Wan's power levels that I am most familiar with are Obi-Wan c. End of Clone Wars to Revenge of the Sith. At this point in time Obi-Wan has moved Durge's ship and used lightsaber throw. To compare Kit Fisto has lifted and moved a massive cylindrical tank and helped Plo Koon shield themselves and clone troopers from an avalanche. So looking at that I'd say their TK is about even to very slight edge in favor of Obi-Wan.
Physically, Kit has run in a blur, deflected blaster bolts, shaped fans out of his lightsaber blows, and moved fast enough to astound Obi-Wan with his speed. As for Obi-Wan himself, he has run in a blur, moved his lightsaber fast enough to create a shield out of the movements of his blade, and flown straight at Anakin while their ships moved at sublight speeds and yet reacted fast enough to veer away from one another. Obi-Wan has also deflected blaster fire from entire armies at once (to be fair though, he did utilize the terrain for cover also). Once again, I'd say it's close, as the two have accomplished many of the same speed feats (such as both running in a blur and making fans out of the movements of their lightsabers). And yet once again I'd say Obi-Wan is the superior by the slimmest of margins on the account of his reaction feat that Kit to my knowledge has not matched. Though at the same time Kit's speed has astounded Obi-Wan...
All in all, this will likely end in a stalemate, but if I had to pick a single winner, I'd go with Obi-Wan simply because while he is only marginally better than Kit in pretty much all arenas that still means he is better, if again, only by a slim margin. So therefore I judge this to be either a perfect split or slim majority for Obi-Wan.
Exar Kun Vs. Starkiller
Ah yes, these two. Exar Kun and Starkiller are two excellent examples of Star Wars characters who everyone THINKS are good but in fact really aren't anywhere close to top-tier.
In saber dueling at least there is no contest. Exar Kun has actually defeated opponents in a lightsaber duel by virtue of being better, which is something Starkiller has NEVER done in the Canon Novel (the video game is largely N-Canon, including the alternate ending). Starkiller was losing to Rahm Kota, Kazdan Paratus, and especially Shaak Ti and Maris Brood. He did not beat a single one of them by virtue of being a better duelist, and even worse, none of them have any feats except for Shaak, who is little better. Granted, no one Kun beat has any feats either, but at least he actually won. Kun was also able to produce after-images from the movements of his lightsaber, which to my knowledge Starkiller has never done. And no, he did not defeat Darth Vader in a lightsaber duel either, rather he bested him via the Force. Before that he held his own against him courtesy of being intimately familiar with his master's unique fighting style. But he did not beat him in a duel and frankly his victory as was is pretty much PIS/CIS.
Now in terms of the Force both of them are frankly rather pathetic. Contrary to popular belief Starkiller did not bring down a Star Destroyer. What he did accomplish was redirect a Star Destroyer that was already falling. And moving this Star Destroyer just a small amount took everything he had and he fainted from exertion afterwards. This does nothing to prove Galen's strength in the Force and in fact actually shows how weak he is more than it does his "strength". And no, he didn't beat Palpatine either. The novel makes it clear that Palpatine allowed Galen to win in the hopes of goading him to the Dark Side as he had Anakin. Having said that Starkiller was able to hold Palpatine's lightning at bay for a time with his bare hands, which is a good feat, especially since RotJ Luke was only able to do that for a short time before being overwhelmed (though it is worth mentioning of course that Galen would have ultimately been overwhelmed too had he not chosen to sacrifice himself).
Having said all of that, Kun's own Force feats are pretty pitiful, especially considering that his Force strength was supposedly being enhanced by a Sith Amulet the entire time. His Force Blast when not enhanced by his Massassi Temple's DS energy was not able to kill a featless individual, and his other Force feats are little better, and to my knowledge he could not ever kill anyone with his Force powers. While Starkiller's feats are nowhere near as good as the title of his story would lead you to believe, he has at least caused far more damage with his Force powers, so I would put him above Kun in this arena, but honestly not by much. Kun can keep up with him here.
Speed-wise, Starkiller is decent, but not the best. Kun was, again able to create after-images from the movements of his lightsaber, so he has that to his name. Neither one has any noteworthy strength feats that I can recall. Ultimately, this could go either way, but I still favor Kun simply because Galen is so abysmal in saber dueling and while he is better in Force ability, Kun can at least keep up with him to a degree. He can also match him in physical arenas.
Qui-Gon Vs. Ben Kenobi
Giving it to old Ben here. His dueling skill may have deteriorated by this point in time due to age and lack of practice, but he was still good enough to fight evenly with Vader, who though not yet in his prime (which was c. RotJ) had still stalemated/defeated an amped TPM Darth Maul...who had killed Qui-Gon when NOT amped. With that bit of ABC logic in mind, I see Ben still being the superior swordsman by a fair margin, not to mention that his excellent defensive skills (Soresu is a defensive form) could allow him to hold firm while Qui-Gon tires himself out due to using a much more physically taxing form (and indeed Qui-Gon is much more prone to fatigue as of TPM).
Force-wise neither one has too many feats to their name that I can recall, and I don't see either one having much to give them any kind of edge over one another, though I do think that Qui-Gon may still take it here.
Speed-wise they're about even, as Ben's being able to hold his own against Vader can match any of Qui-Gon's speed feats. That said, I still feel Obi-Wan ultimately takes this just by virtue of being a better swordsman and being able to outlast Qui-Gon. Beyond that though I have to admit that the two mavericks seem evenly matched in most other respects. Of course given that Qui-Gon's kind of based off of ANH Obi-Wan I suppose that's kind of fitting.
Darth Vader Vs. Plo Koon
This one's a pretty solid win for Vader. For one there's superior dueling feats. Plo's only showing here is doing a decent job against Ventress while having a broken arm, but Vader has stalemated duelists of comparable to greater skill (Amped TPM Darth Maul, ANH Obi-Wan and RotJ Luke). Plo simply hasn't done anything to compare to these showings and in fact lost to Savage Opress. Furthermore, Plo does not have the physical strength to match Vader either, as the Sith Lord's strength showings are far better. And given that Savage beat Plo because he was stronger than him and thus ripped off his breather mask, that doesn't portend favorably to Plo in a fight against another physically stronger opponent.
Speed and TK are more comparable, but the latter still goes to Vader, whose best known feat (destroying a cathedral) surpasses Plo's best feat (collapsing a cave). In all there's just not much else to say about this one. Vader wins by virtue of surpassing Plo in just about everything of note.
And that's all of the fights I saw him post that I feel I can effectively answer. I may do more later if he ever posts more fight ideas. In the meantime I hope you enjoyed my analysis of the various duels.
