Gonna have to go with Marvel.
Don't get me wrong, I'm a GEEEEEEEEEEEEEEEKKKKKKKKKK, and I buy tons of comics every week from DC, Marvel, IDW, Bongo and everyone. Marvel is just the most... rounded. DC have brilliant action, yes, but they're all death and doom. IDW and Bongo have hilarious ones, but no action. Marvel has the perfect all-rounder. Same with their movies. Good mix of both.
