I'm going with Sodam barring lead weakness exploitation.
I'm also not going to bother explaining why, because I feel like I've explained why Sodam Yat Ion was actually pretty serious too many times now. Ignore me if you're looking for an argument.

Sodam Yat is a loser. He couldn't even handle Mongul, and has next to no trans tier feats, especially compared to big names like Hal Jordon or Kyle Rayner.
I don't see it as a lopsided battle by any means. Consider the fact that even after he was nearly killed by lead poisoning, Yat still did better against Prime then pretty much all DC earth's heroes combined previously had... /shrug
