Superman/Silver Surfer (levels)
My opinion.
While there is some overlap, and comparisons can/have been made, these characters are the kings of two vastly different powers sets.
One is THE flying brick, the other THE matter/energy manipulator. Each can do things the other cant. So:
1. Do you just plain agree or disagree with my opinion? Please explain.
2. What characters do you think fall into which level?
For example, i wouldnt call Captain Atom a Superman level character, i'd call him a Silver Surfer level character.
