I like to read a bit about the big guns interacting with not so big ones, that's mostly why I've always prefered team titles, but, ever since a child, I guess I've always been more atracted to the B-C listers then to the A-Listers. I've always prefered reading about the Flash, Green Lantern, Captain Comet (loved SSoSV) and Hawkman to read about Supes, Bats or WW. Wonder Man, Yellowjacket and Hercules over Thor Cap and Iron Man. Cyclops over Wolverine.
Mostly because, even as a child, I always figuered that there was much more that you could do with them.
