I'm going with Bateman because I think he's a more versatile actor. Rudd tends to play the same character with the exception of his stint on Parks and Rec.
I'm with you on this. Paul Rudd seems like a great dude and I like his stuff, but Jason Bateman has a longer and more diverse resume. I remember Silver Spoons man.
So if Jerry O'Connell is a poor man's Jason Bateman, who's a poor man's Paul Rudd?
