By feats Thor > Glads. Not just stength feats, but comparison feats.
It all depends on Thor mindset. Sometimes a peer can give him a run for his money, but he's also stalemated or overpowered opponents thought to be or should be stronger than him(on more than one occasion).
Thor goes to the next level when he needs to. Can't recall Gladiator ever doing the same against such strong opponents. Until I see proof, I'm not going to rate him past Thor.
Fallacy across the board. Either he was 4x stronger than Thor or he wasn't. The result of a fight doesn't change that. All you did was show that Thor has the ability to contend with someone stronger. Thor can't be as strong as someone stronger? That's a contradiction.
Think about it.
Thor used Mjolnir too (it amps striking power). WWH is a lot stronger than Ben. But Ben blasted him good. Being weaker doesn't always mean you can't affect a stronger.
Glads bust a planet with his bare hands. This is much higher than anything Thor ever did.
Bashing a mountain range to pieces is not daycare level nowadays.
A planet is a different order of magnitude.
Thor doesn't have anything equal or greater. Thor's greatest feat (tool assisted) was against Gorr. We don't know how much greater Mjolnir was vs. Thor bare fists. Also, Thor struck Gorr many times. Thus the total force took to do the damage must be divided by the number of hits and then that divided by the number of times Mjolnir increases Thor's striking power.
If Thor achieved the feat with his bare hands with only 5 or less blows then it would be greater than Glad's feat.
Omac - no
Ultraman - maybe
Black Adam - close
King Hyperion - no
WWH - yes
Superboy Prime - definitely
Despero - not sure depends on the showing
Doomsday - yes (classic version)
Gladiator - yes, at his best I think he might be, but the difference is relatively small and Thor can compete. Overall they are similar in power because the hammer evens things out with Glad's speed and strength.
Hyperion - maybe, maybe not. They must be close.
Etrigan - probably no
Destroyer (Animated) - yes
