but zoro really just seems to be set up to be another YC1
Yes he has Enma and could probably cut kaido and its hype and all but there's more to being a top tier than one stat. Katakuri had better CoO than Big Mom and he was not top tier.
While a YC1 might have one top tier stat, an actual top tier has many. For example, Luffy not only has ACoA but FS as well. In addition to that he has top tier speed(snakeman), top tier defense(tankman), and top tier offense(boundman) on top of a monstrous stamina(Luffy vs katakuri). These ultimately add up to make Luffy a low top tier.
Zoro doesn't have this. His fight with Killer proved his stamina wasn't that great, and Zoro has never been a speedster nor has he shown any good CoO feats. So while he will be able to launch attacks capable of hurting a yonko, he'll still ultimately be on par with katakuri. I mean in a fight against kata, Zoro would struggle tremendously. He'd most likely need to use asura in order to have enough AoE to land an attack kata cannot dodge

Luffy aint beating kaido one on one.
still, Zoro doesn't steal Luffy's fight.
In Luffy vs moria, it was a tag team and Luffy still did most the work and landed the final hit
