Yeah, Luffy's always going to be the one to develop faster, and Zoro actively trains while Sanji grows stronger in the same way Luffy does which is simply fighting. I'm just thinking from around Arabasta - Enies Lobby their about the same, then Luffy jumps ahead with his Gears and Zoro and Sanji are still competing slightly behind with Diable Jambe and Asura.
