Aang of course!!!!! I mean like I like Korra and all, but aang was the last airbender and his people died! Atleast he had TEAM AVATAR and Avatar Roku! Korra is good but nuthin compared to Aang becuz he wuz the first Avatar 2 take bending away and give it back just like he did in Sozin's Comet and Legend of Korra
She is almost purely physical (though that is changing), whilst Aang was a good balance of both. However, they are both human beings, and they have to figure things out for themselves. Korra is not Aang, and she never will be. The sooner you get used to that idea, you may start to like her more. I know that i did. I did not like Book One: Air when it was on, but now that i think about it differently (i.e. the fact that the world is SO different) i like it a lot more
come on people! thats like trying to compare Kyoshi to Roku or Kuruk or Yang-Chen! The point of the Avatar is to be balanced, so that they can understand the nature of the people they are meant to protect. Thats why the Avatar is human and not a spirit. The Avatar is from all different nations of all different times to understand how the past influences the future. All different viewpoints and concerns are combined in the Avatar, and they all have their positives and negatives just like human beings. Aang was born as a wise old soul, with his spirituality brought out early, because he was raised as an Airbender. Korra, if you remember, has spent most of her life locked up in a compound for training.
Aang by far, in my opinion. Aang has a relaxed, cheerful personality, but he remains mature and wise in a way. Korra, however, despite being older, is far more immature (in a negative sense) and too stubborn. She was highly arrogant and did not respect others. I'm hoping that recent events have changed her personality because she was a bit of a jerk before. (Conclusion: Aang is childlike, and Korra is immature. There is a huge difference in connotations between those adjectives.)
