Well, Marvel IMHO was far, far better than DC until the Dark Age, whereas the Dark Age was in a lot of ways DC's peak in terms of quality. Of course, that doesn't mean Marvel was complete crap — I just think the '90s stereotypes got integrated a lot farther into their mainstream titles, especially with the X Men spin offs and everything to do with the Clone Saga, whereas DC avoided a lot of it, and actually did a lot of beating up on the anti-hero hype with Knightfall and the Reign of the Supermen.
