Probably either Jonathan or Andrew. Although I've heard more people say they dislike Andrew than say they dislike Jonathan (which I found wacko, not liking Andrew, but it's what quite a few people say).

EDIT: I switched my answer, after thinking about it more and remembering a few saying they really hate Jonathan- but mostly, it's a tie.

I really like Jonathan, but in season 7 Andrew is just a riot, so I had to go with him.

I agree. I swear, not a scene goes by with him in it that does not make me laugh at least once (well, there's the ending scene to Storyteller, and when he kills Jonathan, and maybe a few others, but otherwise not really :P).

Favorite Andrew quote: "This funnel cake is kicking my ass!"

I like Jonathan and Harmony, too, but anyone who has seen "Storyteller" has to agree Andrew's the best.

"I have swimmer's ear!"

It's a toss up between Faith eating the last hot pocket, the Big Board and his mentioning of DBZ (Yes, I've seen all of DBZ)

"that'll do pig!"
so funny , lol

I love every single scene with Andrew! (even the one when he kills Jonathan) And it always cracks me up when he says "Well, I didn't take it, but..." xD

I hate Andrew, is so stupid

Andrew is awesome!!! I like Jonathan and Harmony too but Andrew owns them! I hate Warren.

I love Harmony especially when she became a vampire and when she was Angel

andrew's the man especially in the storyteller.!!

Ahh i hate choosing from lists, but defiantly Andrew and Harmony

i cant stand any of the trio! Gotta go with harmony lol
