My vote went to Leon, but I'm sure you all knew that. 
Let me explain first:
Now, let me start off by saying that yes, RE4 is my favorite of the RE games (well, actually, of all games period); don't discount me as an RE4 fanboy: the only entry in the entire series I don't like is Survivor. I was an RE fan before 4 even came out. That's likely a rare case.
RE2 was the first RE game I actually played and given my age at the time (like 10 at best), I didn't want to play as the "girl" so I chose Leon. He looked pretty cool (outside of his weird super large red hair in cutscenes) and I liked the story surrounding his part of the game.
So when RE4 was first announced to have Leon, imagine my surprise and delight! I actually liked the change in his personality and I didn't think it too much of a stretch to go from naive rookie cop with strong morals to a confident government agent with even firmer morals.
I know others will disagree and I respect that, but these are just my thoughts.
So yeah, Leon gets my favorite character vote.
