To be fair to Supes, he does have some pretty ridiculous high end feats though.
Like taking on the entire Crime Syndicate at the same time and holding his own, with Power Ring, Ultrawoman, and Ultraman trying to beat him down, and singlehandedly and quickly taking down Ultraman and Ultrawoman.
Then there's the stuff he pulled in Ending Battle, facing most of his rogues gallery in a single night and beating them, taking out Power Girl fairly easily, taking on most of the JLA in a Dominus story where it takes the combined strength of Wonder Woman and Martian Manhunter just to restrain him..
PIS? Maybe, maybe not. But when someone like Count Nefaria takes attacks from Wonder Man, or laughs off attacks from big teams that include Scarlet Witch and such, people call it a feat. IMO, Supermans high end stuff is as praise worthy as anyones...
