Harry&Ron, it changes.
But mostly Harry. (Before it was mostly Ron :P)

I'm so sorry Ron (Yes, I am talking as if he is a real person) I can relate a lot to Ron, however he's downright immature sometimes, to the point where I kind of hoped J.K Rowling would have gone through with his plans to kill him off. Harry, although he has annoyed me at one point or another, I excuse him because of the situation where he's annoyed me. I do love Ron very much. ;)

^ I agree with the two above comments, literally word for word. I used to prefer Ron but not so much anymore (at times) but generally Harry.

I really like Ron, I think he is a funny individual and he has amazing family members!

What can I say? He is my favorite boy. I love Harry too but Ron has a special place in my heart.
