Both great series with amazing characters! I have to lean towards Marvel because of Deadpool, though. With his loose grasp of sanity and constant breaking of the fourth wall, the "Merc with the Mouth" is absolutely entertaining especially with his team up with Cable. If you missed it, I would recommend that everybody who enjoys both series read the DC/Marvel crossover books. After that event, they even published some Amalgam comics that featuress the resulting characters.
