If you ask most fans who they think will turn out to be the strongest once we see all the big boys in action, they'll either say Dragon or Shanks, so I don't know why people would be upset if the majority say Shank can beat Kaido. That said, I think Shanks is stronger.
It's not clear at all. Shanks, his men and the ship were completely undamaged when they arrived at MF. That would mean a fight didn't occur between the two crew who are on the same level. Kaido could also be stronger than Shanks, but his crew could be weaker than Shanks'.
Guys it's Shanks.... We clearly heard from Marine HQ that Shanks stopped/intercepted Kaido from reaching MF. Do you realize how powerful you have to be to STOP an enemy, let alone defeat him? It's clear that Shanks is the winner here.
