**possible spoiler**
Why does everyone cite the precrisis Superman battle with He-Man as He-Man being Superman's equal or saying they fought to a standstill?
Superman landed 2 punches & He-Man was knocked out. If I saw a boxing match or mma match & the winner only landed 2 punches in the first round I would not say the fighters were equal or that the fight was a standstill. I would say one fighter got demolished.
Now the new 52 Superman vs. He -Man gave me the impression that Superman is strong enough & durable enough to hang with current He-Man possibly even overpower, but when He-Man stabbed him in the chest I realized He-Man has more in his toolbox than just physical ability. I would call that Superman getting it handed to him.
I think anything before New 52 Captain Marvel would win against He-Man. Current/new 52 I don't know I haven't seen enough to know for sure.
