He used G4 and put hybrid Kaido on his back, a feat that no else has been able to replicate.
If Zoro didn't finish King quickly, he was gonna die, which he said himself, he was essentially on a time limit, that fact is undeniable. As for Zoro taking a nap in a battlefield....
I agree that Kaido is weakened, that is a fact as Yamato straight out said it, I cannot refute it, but you also can't deny that Luffy who has been defeated twice since the raid began is also weakened.
Not sure where how my emotions got involved, but I assure you that I am simply giving you my honest opinion.
I prefer not to get into battle scenarios as they are subjective to our own preferences, for example, I could say Luffy uses future sight to dodge all of Zoro's attacks, or that he is superior in CoC since he is splitting the sky with Kaido, Or that if he uses Snake man Zoro won't cope since it requires someone with future sight like Katakuri to dodge.
It would be more factual to compare their opponents or their respective portrayals, in which Luffy is superior.
