Let's not bring up their stamina as a counter-argument after everything they produced after Big Mom's attacks. It is unnecessary to talk about this any further.
Kaidou didn't do the same thing to Law that Shanks did to Kid, as then we wouldn't have seen him join Kid in the fight against Big Mom a few chapters later, he would probably have been asleep until the end of the story arc.
Kaidou Raimei's Hakke move only one-hited someone once, and that was Luffy at the very beginning of the story arc. Then this miraculous ability passed.
The same thing probably would have happened to Law if he met Shanks and not the other way around, but hey, Law is ahead of Kid in strength, just because. Why would I say they were equal against Kaidou or Big Mom when that's simply not the case? I think even Killer hurt Kaido more than Kid.
Lol, are you afraid to mention me? Of course, what Shanks and Kaidou did wasn't entirely identical. How can you assume that Kid wouldn't return after the attack in the same way Law did? Shanks needed the help of the giants to sink Kid into the sea, and Kid is a Devil Fruit user... He could very well come back after Shanks' strike, just like Law woke up after some time after Kaidou knocked him out. The
difference is that Kid fell into the sea while Law did not.
How is their endurance not an issue when Law explicitly mentioned it in the chapter?
Okay, start by using your awakening that drains your endurance faster against endurance and durability monsters. Kid and Law's final attacks couldn't even knock out an exhausted Big Mom, and you want them to start using these moves against a fresh Kaidou and Big Mom? Good battle IQ. In the end, Kaidou or Big Mom will just tank all their attacks while Kid e Law they're lying on the ground exhausted. Just like it happened against an already tired Big Mom.

Luffy in 923, Law in 1009 (and didn't even hit him in the head), Yamato was still falling to her knees even though she defended herself.
Law >> Kid In terms of reaction speed.
A Kaido's Bagua would finish off Kid in the same way or even worse than what Shanks did to him. LOL
