It definitely is hard to pick a particular favorite, they all have their moments in the show. If pressed though I would have to give it to Bender, the unpredictability just adds lots of fun to the show.

I'd probably have to say Fry as well, he just is very genuine, cares about his friends. Bender is also pretty great for a laugh.
Probably Professor Farnsworth. Each of his lines raises a laugh or a smile. Also, he invented the finglonger. I mean, where would we be without that? The Dark Ages, I tells yer.
Honourable mention to Dr Zoidberg. But seeing as he's Dr Zoidberg, he can't come top, so there!
Leela, and not because I had a crush on her as a kid.
She's strong no nonsense, but pigheaded enough to make mistakes. Still, her heart is always in the right place.
Probably Scruffy, the janitor.
Why are you not fixing the boiler?
Zoidberg. He somehow manages to be the comedy relief in an already comedic universe. And I was so happy when he finally got a win in the finale.
All of them...even, like, mop bucket...and Cartridge bot... and the turtle!
