Luffy and Joe are similar in a few ways. They're really strong, have a lot a cool tricks up there sleeves, protect their friends, and are really funny. With both Luffy and Joe, when I first started watching they both came off as annoying but i grew to love 'em both.
Other than that VJ and OP both have great action scenes and a decent plot.
