This is a terrible debate because Supes Prime 1M is featless. He could destroy universes for all we know, but he has no feats to back up the mythos. Its not that he's been shown to be weaker than WPOTC, but he has no feats. Someone please lock this thread.
@TerryBogard2014: spite is creating a match where it is intentional which will side will win. This is sometimes done to inappropriately prove a point. I think this is more of a mismatch. A good example of a mismatch would be Superman vs. Squirrel Girl (without PIS).
