One thing I noticed about this chapter is that the fight ENDED FAST. And it doesn't mean it's an easy clash. As we all saw, Oden wounded Kaido a heavy wound.
But this is something I also noticed with another TOP TIER fight in Marineford (Whitebeard vs Akainu). The exchange truly ends really fast. Where every blow is as lethal as it gets.
This is important because I used to think Luffy has a durability problem when he faced Kaido.
But that's NOT TRUE considering Oden got the same amount of Damage from "Tunder Bagua" as Luffy.
Which makes me believe that when Oda announces fights of Top Tiers lasting "3 days, 5 days, 10 days" They usually do not go FULL POWER from the start.
They may start the battle with a King's haki clash that is so big as a way to say "Hi, long time no see"
but they usually bring down the tone, and they preserve their energy and only go all out and reveal their biggest moves in the very end.
Which is why, when it comes to an ALL OUT WAR:
WB vs Akainu (Lasted few minutes)
Kaido vs Oden (Lasted few minutes)
Because in those fights, it was not a mere confrontation. It was an all out war, and they bring their biggest moves from the start. Every blow is as LETHAL as it gets.
What I'm trying to say is that... Luffy now appears in a MORE respectable way, because what he suffered from Thunder bagua is now expected since it's also the same move that took down Oden.
