Patronus, it's actually interesting that you say you like DC because you like your characters less indestructible, because I think overall, the expectation is that DC deals more with god figures and Marvel more with men. In the overall scope of the DC vs Marvel Universe that is absolutely true. It's why I'm always quick to point out that I stick with more of the Batman arc than anything. (Batman, Batgirl, Dick Grayson, Jason Todd, Tim Drake, Jim Gordon etc) Honestly, my favorite aspect of superhero based comics is the character of Robin and how the different people to be Robin have dealt with that role. I'm absolutely hoping that Harper Row becomes the new Robin, but that's another topic entirely.
Beyond that guys like Oliver Queen/Green Arrow etc. I guess I'm a sucker for flawed vigilante types with with a moral code. Interestingly, I've been getting into Marvel more as a result of the Iron Man films - again, rich guy with no powers other than an unlimited budget. I wonder what Frued would say.
I don't really care as much for Superman, Wonder Woman, Green Lantern either, but as a child I think I just got more comfortable with them than I did Thor, Hulk, X-Men because I would watch Super Friends and Justice League for Batman.
