Marvel is more centered on using real-life places to tell stories about fictional characters, whereas DC bases almost all of their stories on fiction (characters and places) in almost all of their stories. This will give more personal reaction to Marvel stories rather than DC. That's one big difference.

Continuity of characters between stories was always a big point Marvel made (at least back in the day... now not so much) while DC has taken that over (at least from what I know or have seen on the DC side). You might even ask both sides about what they like most about the publishers and then try to make a comparison that way. It might be kinda biased on the Marvel side if you don't. ;)
