i recommend geats not be your first rider for multiple reasons, but primarily because i think the strongest series that are easiest to get into the kamen rider zone with are in heisei. kuuga and ryuki are considered the best of the best, and i agree, though neither are my absolute top favorite (they are my paired #2 though). what you should watch first depends primarily on your own taste aside from that, but i still wouldnt start anyone on geats, even if you like foxes. if you do watch geats, do it after a few other ones......... any other ones
