Eh, it's kinda common knowledge WonderWoman is a step below Superman.
I think they let her stalemate with him because of her fanbase, she shouldn't be able to last long against an angry Superman.
I'm no Superman fan, but I know what he can do when he's pissed.
Whirly knows his Superman/Gladiator background, he should give the link of the "First Superman", it's hella interesting.
DC and Marvel both copied superman from the Gladiator guy from the book.
And,(I'm not defending) but Orion knew Darkseids weaknesses and ways to take him out when he killed him, Superman knew next to nothing about him. That in itself gives a bit of prep to Orion.
I can't remember, but I believe Orion deflected Darkseids Omega Beam back to DS with his bare hands, I'm not sure Superman could do that though.
