Then it flips Superman on his ass, because then he isn't even close to the strongest of the fuckers roaming Earth when he's presented like he's one of the pinnacles around, if Ares or Hades can smack the taste out of his mouth he's nothing special, which they absolutely present him that he is.
Whereas when they present someone strong in Marvel, its undeniable, even if they boost someone later, like Jubilee, they caveat it, but someone like The Sentry is pretty much top tier, remains top tier, and is held back by his various flaws, they don't wobble his power level around other characters like they do Superman, which is ironic as The Sentry is supposed to be the mentally ill expy of Superman for Marvel.
