DC. Because i found Marvel more kidish, less dark stories and less complicated heroes than DC. (sorry for my english)

Marvel because it has thor, thor =autowin

Marvel. More interesting characters IMO. Spider-Man and the X-Men were always better than Superman and Batman as far as I'm concerned.

Marvel of course...
simple
Deadpool>Deathstroke

Marvel :)

because they have many cool heroes .

DC has better villains, while Marvel has better heroes.

Are you running some type of experiment? So many X vs Y threads lately.

marvel
more intresting and diverse heroes
no superman
better storylines
better games
better shows
better movies

Marvel because I like the heroes better

DC because Batman. Also, not being a comic reader, my experience is limited to other media. I think DC's animated series/movies are much better than Marvel's. I watched the heck out of Justice League and Batman The Animated Series as a kid but I really didn't like the Spiderman or X-Men cartoon. DC Animated Universe movies have all been killer as well. As for live action movies, well Marvel has the lead by a country mile, but then I loved the Batman and Robin live action movie, so what do I know?

From my experience and my taste Marvel has the better comic books, while DC comics has the better cartoon shows. Seriously nothing can beat Batman: The animated series.

Spongebob Squarepants .... Where is your god now?

DC. By far. Marvel needs to get their crap together. Marvel NOW was a big flop with me. While the New 52 was a great move by DC.

I've got my likes and dislikes with both.

Tintin is the best

Marvel, Their heroes actually have some thought and feeling behind them.

Vertigo, obviously! xD

DC

I love batman: Comics, Trilogy movies of Christopher Nolan, games from RockSteady.

Its 50/50 for me... :)

DC because Batman.

Marvel. More Realistic over-all imo (or they just do a better job of explaining how their heroes got powers lol)

I don't honestly know a lot about the both of them... but based on the characters I do know and like, I'd have to say Marvel 100%.

DC for Superman and Batman

Laff you should have an era option - marvel ruled the 60s when DC was becoming stagnant and was a breath of fresh air. Marvel edged the 70s with deep topics (eg rework of x-men), but DC caught up with edgier batman stories etc. 80s was pretty much even and for me DC has edged ever since with more mature options. Having said that I'm enjoying the marvel movie options more than the DC ones so far ;-)
