>Nepo
Zoro, I initially had Zoro borderline since teh shimotsuki bloodline has not been relevant since Ryuma but Zoro has a super trainer with Mihawk so I'll say he's nepo

>borderline
Sanji, was technically born as such but cut ties to it early on
Robin, Depends if you consider Ohara scholars legendary trailers but idk for Robin but she did sell her body to get into baroque works
Chopper, also hard to say for his doctoring he technically is a nepo in that sense but a lot of things he figured independently
Franky for his craft was associated with the best builders in the verse in current time, he's my boy but I have to be objective
>non-nepo
Jinbe, really just been more of a carnie getting into big agency then a nepo
Usopp, didn't really get any help from his dad at all and was trained by a literal who
Nami, this one is surprising looking back, she really isn't nepo at all
Brook, though it appears that might change
