If Zoro is using King of Hell Form Without CoC
And his Performance is 9/10 against Awakened Lucci, then it seems that:
07. Base Luffy
06. Gear 4 ~ Base Zoro
05. Gear 5 ~ King of Hell
04. Base Luffy (CoC) ~ Asura
03. Gear 4 (CoC) ~ Base Zoro (CoC)
02. Gear 5 (CoC) ~ King of Hell (CoC)
01. Asura (CoC)
Basically both have Three Forms & each Form can be Upgraded with CoC
But Zoro is always Superior when comparing same Forms
