You’re literally saying yea that happens in the manga ..but what if it was Sanji. Ok your point is that’s just characters opinion of zoro based on word of mouth in the one piece world. But what’s your opinion is zoro not obviously depicted as stronger and with superiority in the crew?
My point if the entire argument is based on headcanon and "well Oda put it this way so it must be telling us something". What it's telling us is simple.
Is Zoro depicted as stronger? Yes, obviously. Zoro is very clearly presented as the stronger of the two almost all the time.
Is he depicted as having superiority in the crew? No. As I've said. There is no vice captain. Anyone can talk over each other. Nothing supports the notion that Zoro has superiority to anyone
