Wolverine wears a mask and gloves, though. From everything I've seen from Sauron (which isn't a lot, admittedly), he touches skin to absorb life force. Going in character, Superman, bare hands and all, is going to start off the confrontation by touching Sauron, either with a flying double punch, or by sneaking up on him and chucking him out of the way. Stuff like that will work against Superman.
I'm not even saying Superman would lose here, just trying to bring up some points.
Judomaster's whole shtick is that she can't be hit. Unless X-23 could outlast her, which some might consider unlikely considering how many blows to the head she'd receive, then Judomaster would take it.
Supergirl may have been able to take those punches from Reactron, but Supergirl has regularly been shown to be stronger and faster than Power Girl, even if all of her feats have been inconsistent with one another, so I doubt Karen would be able to take those punches from Reactron like Kara did, nor do I think Power Girl would've remained conscious after that star explosion move Reactron pulled on Supergirl in his first appearance.
