@lanternbatman: Not the blast part. The first two scans: stunning Deadline and nonlethally dispatching all his men while the dog remains suspended midair. It's more impressive to me for two reasons, basically:
Deadline himself has superhuman reflexes.
He's taking out less men, but he's moving all around the room to do it.
I just see Deathstroke as someone notably all around superior to most other street-level metahumans physically, and by a decent margin. Not to the level of say, Spider-Man or Gorgon; more like a Black Panther or Sabretooth kind of deal. Anything up to par with that is going to put the New-52/ Rebirth version up to par with his classic self, thus above Bruce.
@morpheus_: I can see where you're coming from, but with a little more scrutiny, I come off viewing Slade as superior in all those encounters, save for King which was just flat-out PIS. He was weakened physically and, perhaps more importantly, hindered skill-wise under Daniel and he still essentially defeated or otherwise outfought Batman by the end of the issue. Under Bendis and Priest, he already had exactly what he needed to keep him off-balance and got murked as soon as Slade manipulated him into coming in too close. Otherwise, fighting evenly with a prepped Batman with nothing but a combat knife demonstrates a destinct edge to Slade, as far as I can tell. Moreover, his strength was shown to be wholly insufficient to damage Slade in the first issue of the Deathstroke vs Batman arc, as he seemingly doesn't even feel Bruce nabbing him out of the air and choking him with a chain.
Whether or not Slade does pull a majority, which I concede he may not, I definitely disagree with Bruce boasting superior combat speed. I don't believe either of the showings Fetts mentioned are his best feats. To me, his first fight with Deadline is much better than the yakuza feat.
Finally, we arrive at Rebirth. About a year ago in issue #16 of Priest-Stroke, Deathstroke took on Deadline, a metahuman himself, and a number of his goons. He actually runs up to Kyle and stuns him with the blast stick while blocking a shot of his with his elbow, gets back in the air before he collided with the table Slade sent him into, and skillfully incapacitates five of his men all the while a lunging K-9 unit remains suspended in midair. He then reacts to the Infinity Rifle which Tanya Spears Power Girl failed to accomplish on the subsequent page despite having slapped bullets out of the airin the issue prior. Again, this feat becomes increasingly impressive after taking a look at the full context: not only was he managing a conversation with the Ikon suit's built-in artificial intelligence, but he also previously announced himself, giving all these men fair and decent warning.
I consider post-Flashpoint Deathstroke as physically equal to his New Earth self if not superior in some categories, meaning I disagree with Bruce holding any advantages in stats, but I don't want to argue all that out. Take from this what you will. IMO if Batman wins, it's due to skill.
「I stared Death in the face, left him with a sore neck. Gaz and the others should've told you what we found there, if they made it back. Something like nothing else, is what it was; way too dangerous for them. I hurt it good, but it bolted before I could finish it off.」
I'd still go with Slade, personally. The only area post-Flashpoint falls short of his New Earth counterpart as I see it is skill, and he's still very formidable therein. If he doesn't give Bruce the chance to trip him up with more raw skill like under Wolfman, then this is going about the same way as their encounter in Detective Comics #710.
The phantom assualt soon became too much a test for the skills and reflexes of Gaz and Rocs. Hera, being faster, had it easier. Des did too, but the moves necessary to keep alive came naturally to Ms. Fingers.
「Chess moves are made, my third eye ain't blinking.」
Rollie was mindful of the ensuing casualties. Seeing as they contributed nihil, she ordered Gaz, Rocs, and Hera to make off with Wedh and Mateo and inform Ma of the situation. In a supernatural exhibitation of accuracy and timing, she preemptively eviscerated a lethal tendril meant for Rocs and halved a set of teeth before they could meet with Gaz's left leg in one cut.
Without need of protecting the others, the remaining siblings finally made their push on the wolf. Des moved first, protecting himself and Rollie, violently bashing different beasts aside as the aura of her blade weakened them. When the point of her sword met the wolf directly, the dark magic would cease.
