Let me make it easier for those Coping
For Zoro to be Comparable to Luffy: (Either Add or Remove CoC to Both)
1. If Luffy needs Gear 1 to Defeat an Opponent --- Zoro must only need Two-Sword Style
2. If Luffy needs Gear 2 to Defeat an Opponent --- Zoro must only need One-Sword Style
3. If Luffy needs Gear 3 to Defeat an Opponent --- Zoro must only need Three-Sword Style
4. If Luffy needs Gear 4 to Defeat an Opponent --- Zoro must only need King of Hell Sword-Style
5. If Luffy needs Gear 5 to Defeat an Opponent --- Zoro must need Asura Sword-Style
I'm not saying these Forms are Equals or Same Levels, but They represent Comparable Milestones of how much Luffy/Zoro are being Pushed.
So for Luffy to Replicate Zoro's Feat, He must Destroy Lucci without Gear 4/5 or CoC
And for Zoro to Replicate Luffy's Feat, Lucci must Survive Three Asura Attacks lol
Aside from Nightmare Luffy which was Situational Form,
Luffy has never ever been Stronger than Zoro
