Zoro been Sanjis rival and portrayed as equals since long ago... they fight villians of same strenght and are both wings of PK... Why does zoro fans hate the story as its told ? They make up bullshit theories like ZKK that are filled with head canons and hopium... and when they headcanons fail they quit in anger rant and insult everyone even Oda... when the story is actualy very consistant
As a zosan simp, sanji and zoro can be equal, but not in strength/combat power, because :
1. Zoro's role is a fighter/combatant
He should be better than all nakama in this regard, just like how sanji is better in cooking than everyone.
2. Sanji has many other abilities beside fighting
Cooking, stealth, flight, invis, etc etc. So sanji must be lower in combat strength to balance them out. You can't make sanji zoro equal in strength, but sanji also has many other skills, he will overshadow zoro. If you're fine with this, probably you're itachi fans.
