I was just talking about this with somebody the other day, and I realized that all my favorite titles from DC (save for GL) exclusively come from their Vertigo line. The line where DC basically took the lid off and said, 'Okay folks, have a field day!' These titles generally tended to be more visceral, more empathetic, more down to earth than the main DC line. There was mythology to them, and that's something that Marvel has always done well. No matter what, Marvel comics felt like they all belonged in the same universe, had history with each other, and generally did a superior job of worldbuilding. Vertigo, especially with the Sadman, Hellblazer, and Swamp Thing titles managed to capture that as well.
