Sasuke: for being more what I imagined a real life ninja would be like. (I do like Naruto (4th favorite character) but when I think ninja I don't think orange and idealistic). Sasuke on the other hand shows how a flawed character would respond the a dark world like Narutoverse. I've always seen this as more realistic. In Part 1, I liked how he was calm and always collected, but this isn't true anymore, though he seems to be improving.
