Apoo: Knocked Luffy out
Kaido: Knocked Luffy out before he learned adv CoC, making him very unfresh.
Zoro: didn't push Kaido to his knees.
Kaido also has zoan regen, Luffy doesn't.
A "fresh" Luffy is now automatically a LOT stronger than what he was when he started the fight, now that he has adv CoC, it is debatable how much other characters did in terms of damage, Luffy put Kaido down for a few pages due to G4 Internal damage, nothing has come close to that.
If you can't understand these basic differences you have issues.
