NOTE: I'm not asking who would win in a fight, just which one you prefer.
They don't necessarily have to be the same character, but should fill the same sort of archetype
For example, The Green Lantern Corps vs The Nova Corps. (space cops)
Batman vs Iron Man. (super heroes whose main power is a lot of money gained from weapon contracts)
Superman vs Captain America. (All American heroes)
The Monitors vs The Watchers (we ain't gonna do shit)
