Zoro is barely a character if I’m being honest
He’s just Luffy with 3 swords and a more serious demeanor
Oda literally created two of the same characters and that’s why both are so highly praised
I am not sure lol
Because they do share some similarities..Zoro and Sanji also share some similarities hence why they are at each other's throats all the time.
But Zoro is different from both where it matters.
He is there to stand up and be a voice of reason when rest of the crew is being wasted drops of ink and just dick riding Luffy.
Zoro showed level headedness in Water 7 with Luffy and Nami
Zoro stood up against Usopp
The latest chapter
He is clearly not as dumb and clueless as Luffy.
Then there is the overall moral compass and sacrificial nature of Zoro..He has well defined goal and catalyst for his Goal being Kuina yet he managed to evolve from that and add Luffy and his crew to his motivation saying he isn't even worthy of being WSS if he can't protect his captain and crew in Thriller Bark.
Zoro constantly evolved as a character pre time skip adding more and more layers to his characters where as Luffy just remained the same.
Sanji also evolved but for the worse.
