👆 it wasn't even shown. I just found it hilarious that it was what underpinned Carv's opinion, and then a page later he's asking for feats of the characters Supes defeated...Anyway....
This is what paltry feat I could scrounge:
DCeased Superman was able to break DCeased Darkseid's jaw:
Darkseid was a planet killer:
Superman was able to operate on a nanosecond scale:
Was able to be at the depths of the ocean without breathing apparatus:
Took Cap Atom's blast at point blank range (as did WW), which grew from Washington to Baltimore to Metropolis, and was the most destructive explosion ever unleashed on the world (and was heard/felt all around the world):
According to this site, the most destructive explosion on Earth was the K-T extinction event that wiped Bada's people out:

Was fast enough in travelling and reflex speed to hit Barry, hard enough that his fingers were embedded in him:
That's pretty much it, I think. The main feat is Captain Atom, and we know WW survived that blast - but Superman casually punched through her. That, plus the nanosecond feat.
All in all, I don't give two hoots about whether these feats are enough to sway people's opinions. I am just laughing at the idea a mere statement and off panel battle was enough to sway others opinions, whilst they simultaneously ask for gold standard levels of proof.
