At this point its very hard for me to disagree with someone saying Kaido is a whole tier above Fujitora.
Like lets check that
Kaido has faced 9 samurai two of whom are possible Sabo level and got roughly zero damage.
Kaido has faced Zoro who alone can defeat all four revolutionaries including Sabo and took an attack that can kill any character dead of Live in a single attack
And now he basically low diffed Luffy
Who had one power up
Post WCI Luffy - Sabo Level
Post Udon Luffy - 1 level above Sabo
Post AdvCoC Luffy - 2 tiers above Sabo
And Kaido took roughly no damage from him. Only character on the roof who has done anything relevant to Kaido, the only character who was any threat to Kaido was Oden level Zoro but even he is mid/high diff fight at best.
I am pro admirals but Oda has hell of a lot of explaining to do to convince readers that Fujitora and Kaido are same tier
