Because I keep hearing Aang advocates say he has more feats I'd like to hear what feats you're referring to. I'm just saying, a lot of his feats were accomplished because of assistance, direction of another, or the avatar state. I'd also like to point out that his enemies weren't all difficult, as on not all of them were. Yes, he had his difficult few which were to be significant characters at the time such as Zuko, Azula and her team, The fire nation archers, "Sparky Sparky Boom Man," the Earth nation elite guard, and Ozai, but other than them can you really account for difficult enemies? As (((Prodigy))) stated numerous times before, which I don't know why you don't take the time to read since he/she took enough time to back their source, his enemies weren't all difficult, only an elite few. As for Korra, she has Tarlock, Pro-benders which are very good so please stop counting them out, Amon who is a blood bender who has perfected it's art enough to take bedning away, and an entire fleet of anti-bender chi blockers who were all using weapons. They're basically like Mei and Tei-Lee combined. You can say Tei-lee was a better chi-blocker if you want but the chi-blockers in LOK were very competent and beat a lot of master benders by use of stealth and guerilla tactics. Korra also had to fight advanced tanks that could take on multiple benders which were superior to just about all machines the fire nation used to have. Korra also fought in Pro-bending which you have to admit is quite a fight. Point blank range where you have to strategize on the spot and dodge by use of your muscle only. I'm just saying, don't underate the challenges Korra faced; she only had one season to do this all in which was also in a shorter span of time (her time) and the season was rushed too mind you, since they didn't plan on making LOK form the beginning. Aang developed most of his difficult enemies by the midway point of season two and then later in season three.
I'd also like to point out that Aang was pushed to the wall multiple times where the only reason he escaped was because of Avatar state. He's transformed quite a number of times if you look back. He's beaten a lot of enemies, yes, but he;s not this godly powerful character that you keep describing him as. He's nearly lost to a lot of guys who aren't that strong in comparison. Also, the tatoos come from the creation of a new technique called the air scooter, not mastery of air bending. Just read the wiki. The depiction of mastery seems to vary in the bending community since obtaining the status of master in air-bending came only form the creation of the air scooter, and yes it was just because of that. Again, check to wiki. So, personally I'd say Korra could win 2 out of 3 but I could also see Aang winning, it's just not the "stomp" that people keep thinking it is. Just cool your jets about who you think will win, don't take comments personally, see things from another person's view, and count the things going agains your own character you're rooting for, because people seem to think ai-rbending is far better at handling opponents than any other. Just reminding you, all the air benders were wiped out by the fire nation and they had temples all over the world which would give them more strongholds to take advantage of and Aang had to resort to the use of the environment more times than taking his enemy out by the use of air. I am impressed by his handiwork just like I am Korra's but I'm not going to blow things out of proportion and say one person is vastly more powerful because there's a lot of things to take into consideration. Aang hasn't fought against anti--bender users. Korra has been fighting primarily those and hasn't really had a need to pull of a feat since they were either in a cramped space, didn't use avatar state, or isn't suposed to destroy the city which is cramped as is. And lastly, please read what previous arguments say because a lot of recurring statements have either been discussed, explained, or countered. I say this because a lot of those for Aang advocates have been ignoring reasonable points made by others or just say Aang wins without an explanation with facts to back them up.
