Loki and Imu are build different.
Luffy is stronger than Kaido.
Only Kaido fanbois argue against it.
Luffy barely learned adv CoC and matched Kaido one... he was fighting high tiers dude. The damage he got are from high tiers.
And except Zoro none supernova used their super moves. And even Zoro got stronger after his Kaido battle to beat King.
Look what Shanks did with Kid and Killer, something Big Mom or Kaido didn't manage to do.. with one crazy adv CoC attack.
It clear that Kaido adv CoC or Linlin one aren't that high and they also didn't awakened their df powers. The more we learn and see the more it is clear, Kaido is behind characters like Loki, Shanks,Akainu, Blackbeard and co.
It is only matter of time until it became more clear.
Shanks and Loki are already prove that.
I don't see them weaker than Kaido.
Luffy and Bumkainu ain‘t stronger than Kaido.
It is actually more embarrassing for an awkakened Luffy to barely beat Kaido, after the gauntlet Kaido ran.
Also it was highly implicated that him carrying Onigashima fucked up his stamina and yet Kaido was still easily capable of fighting G5 Luffy.
The fact that Luffy‘s strongest attack still struggled with Kaido‘s last move despite being having gravity on his side, isn‘t looking good for him either.
Kaido 100% vs G5 would still be an extreme diff.
Also if Kaido was awakened, it would be worse for Luffy. Elbaph level Luffy isn‘t impressive what so ever and Imu would destroy Kaido too, but Kaido would still put a better fight than Luffy.
