If Kizaru has another gear and awakening, I'd have to agree, Kaidou looks bad. This is Luffy going all out, and Kizaru still seems relatively unfazed.
I don't even know what the intention here is from Oda...is he actively trying to show Kaidou ain't all that? Or is he just trying to show the fandom how strong an Admiral is supposed to be?
One interesting scene is when Kizaru admits Luffy has the strength to take down Kaidou, and then bodies him right after. Keep in mind even base Luffy was impressive against Kaidou, and G4 Luffy looked useless next to Kizaru.
All agendas aside Kaidou might just have been fed to new mode hype.
