While I love Zatanna as a character and concept (and she's really the only DC character I'm interested in comic-wise), I think Marvel also has a really strong magical/supernatural corner. It just is drowned out by everything else, and usually just represented by Dr. Strange in crossovers.
Marvel has some nice entities in supernatural corner, but they just don't compare to onslaught of truly amazing stories and characters DC put into their mythical corner. I like Zatanna too, but in DC verse she's is pretty small potatoes compared to A-listers, like Constantine, Spectre, Sandman, Swamp Thing, Doctor Fate or Timothy Hunter.
DC just has a lot richer and more developer supernatural side and one that has delivered far more classic stories. On the other hand, even with the Geoff's valiant Green Lantern effor, I always found marvel cosmic side to be far better and richer than DC one.
