Zoro already stronger then most om rhe list once he unlocked advanced conquerors haki. Law even when using his awakening still uses a zord and bb was able to counter it with an attack. Zoros swordsmanship 10x better he also can block all movement inside of room. Kid he just to slow and easy to hit. Yamamoto is a beast her and zoro close to even b4 entering elbaf. Sabo is a powerhouse but luffy was able to grab and hold kizaru when using Conquerors. So I think zoro might be able to cut Sabo but luffy was in gear 5 so that could be the reason he was able to hold kizaru. But he is the only person that might beat zoro even though he hasn't done anything imo on the level of clashing with with an elder.
