I love hearing about comics from decades ago, and how each of the major houses handled their stories and characters. I feel decades are great for defining times in comics.
So between DC and Marvel, who "won the 1970s"? Who put out the best material, characters, stories in the 70s?
Chris Claremont's X-men stands out big time for Marvel, but then there's Len Wein's Justice league and Denny o'neil's batman revival. Hard to chose!
