hard to say any clone could beat superman. supreme was more savage but superman would beat him. supreme doesn't have the speed feats nor the strength feats. i happen to like supreme a lot--i think i have every issue he's appeared in--but he wouldn't take more than 3/10 from superman.
hyperion--not even close imo. when he first came on the scene maybe he'd have given clark a run, but i see him doing much worse than supreme.
glad's has potential, but again, until he's better defined as a character, no way he wins, imo.
majestic i think is the strongest of the clones from what eny showed, but his durability appears to be somewhat less than superman's. i'd give clark 6/10 against him.
comparing characters to superman is next to impossible. just too damn many feats to contend with. 😬
