Depends on how you view his conquers haki.
A:) Made a whole state from Conquores haki keep in mind this is unintentional (Asura) I don't think @HA001 OF THE RAIN and @nik87 agree Asura is advCOC though I think it is.
B:) Scarring Kaido is a feat only matched by Oden this in itself should put him above, I know you think the blunt attack from Yamato should be a feat but she merely scratched his head, then which we have to take into account the scabbards with their swords Kaido states doesn't compare to Oden
C:) Made another mode/state with AdvCoC & AdvCoA this is another "+" for Zoro.
D:) We also see Zoro consistently damaging King with AdvCoC while Yamato did minimal damage to someone less durable.

B) Splitting the sky is only a feat matched by Shanks, Roger, Whitebeard, Kaido and Big Mom. See how that works? Oden was many times weaker than Whitebeard, Roger and Current Kaido.
C) How is it he just gave himself a title?
D) Yamato was damaging Kaido. Damaging someone with a blade is significantly less impressive than damaging someone with a blunt object.
