Who's the better character?

I'm brainstorming writing an essay about Zuko and Edward, comparing their characters and discussing which is the better overall character. To be fair for Edward, I will reread the Twilight Saga. *twitch* I hope to explain to the Twitards that Edward Cullen isn't that great of a character.

I'll be talking about both of their personalities, their relationships, their character growth and other yadda yadda. Since I'm an avid Avatard, I think Zuko's side of the coin with be fun. However, Edward's will be more difficult, so it will take me some time to write up his.
