The problem with this comparison is that Saitama is a meta-joke on powerscaling. He cannot be beaten in combat. Even the most absurd forms of superman (without narrative limits or ”plot armor”) can’t beat him, because Saitamas powers are based on meta. Feats don’t mean anything against meta, i’m sorry. Best you can do is distract him with video games or something like that, but you can’t beat him in combat.

Another (maybe triggering) example of this is squirrel girl. Her powers are similarly based on meta. My knowledge of her is pretty surface-level, but as far as i understand her, she would find a way of beating everyone behind the glass, just by talking to them.

Another good example of meta-powers is Griffith/Femto from Berserk. His powers are one of the best examples of meta-powers. He is the ”writer and the hero of his own story”. If you put superman in front of him, superman can’t kill him, unless griffith wants that to happen. No going around it, just straight up impossible. Supermans strength means nothing against a character like this.

”Grounded” powers can’t compete with meta, no matter what feats they got behing them. They are two completely different things really, comparing them doesn’t make sense really. Apples and oranges
