I vote for that Jaguar3529 guy, by process of elimination.
Although Conkerzilla's is funny, it looks rather like what Boxiom did for smoshsurvivor when he was stoned.
EDIT: Familiar?

Kristin's is seizure-inducing and I would rather shoot myself in the face than look at it.
LostCanuck's is kinda boring. Not bad, but boring.
ButchTheHobo's is pretty good, but I'm mad at him. And honestly, even if it was done by someone else, I still wouldn't vote for it. Something about it just annoys me.
DreadfulFlame's isn't very good.
Lara's is crap.
Pirategirl's is sweet, but not very attractive.
Alex... No comment.
It was really between JackMehoff and Jaguar, and I choose Jaguar because it's more smosh related, and come on. Penguins are the cutest things EVAR.
JackMehoff gets an honourable mention from me, because it made me laugh, and is very well done. But there's just no beating a penguin.
Merry Smoshmas!
