When it comes to role, actions, and personality, yeah. The only real similarities between Zoro and Rayleigh is that they both have scars, they're swordsmen, and they drink. By this logic, Zoro is also this generations Shanks since they both are swordsman, have scars over the same eye no less, and both love to drink. Hell, they even have strikingly colored hair that gets pointed out. This is how dumb these "This guy is the that guy of this generation" shit is. They're not, they're just their own people having their own adventure as Love Cook said. You'd think with all the times Oda has explicitly pointed out parallels between Luffy and Roger, that if he was trying to do the same with Zoro and Ray, there'd be at least one explicit indication of that too.
