The only DC (except imprints like Wildstorm) I'm thinking about getting is the Wonder Woman reboot (Yay! Non-Scantily clad women!), but everything else is (to me) dull. Superman is dull, Supergirl is Superman but female, and in nothing but a bra and mini-skirt, Batman
isn't a superhero - he's just a bloke with a lot of money and toys. That said, I care little for a fair few Marvel heroes too - Cappy A doesn't interest me (will watch the film, though), Spiderman is overused and boring.
If I had to choose between both, it'd have to be Marvel. Deadpool, Great Lakes Avengers, Lady Deadpool, Deadpool Corps, Marvel Her-Oes, X-Force, various X-Men comics (Note: Not really an X-Men fan), Thor and a few others just win it for me, though. Oh, X-23
