Dc. Mostly because of Batman but if it ever came to a close with marvel, then dc would still win because of what pre-52 Superman represented, he was an all powerful demi-god and yet sometimes more human then any other superhero I have ever seen. Bonus points to Rorschach since he is part of dc universe as well.

I'm only really interested in movies, and DC just can't seem to make good ones. Marvels extended universe ranges from moderately enjoyable to amazing, DC is consistently garbage. (Including Wonder Woman!)
It's a pity DC ended their Dark Knight series for their extended universe. What a waste.
