Marvel and DC came of age at different times. DC came around in the fifties where everyone was Mr. and Mrs. perfect living in suburbia surrounded by white picket fences. Its natural that such an optimistic time wouldn't relate to a modern standpoint. Marvel is simply younger and more cynical, which is why most people in this day and age would pobably fiind it to be more believable. But then again, the Big planet destroying ubervillan of Marvel is a guy wearing a Pink helmet and a dress...apples and oranges.
