You are basing what clan is stronger off transmigrants. Im basing this off overall clan ability and the majority of people associated with said clans. Gedo chains and Susanoo are not even equals. Im not saying Uzumakis didn't have potential to be as strong as Uchiha back in the war times but they were mainly sealers. While Senju /Uchiha were frontline fighters.It's rare because it's capable of stopping the likes of Kurama, it's no different to Susano'o being rare because it can fight 1v1 against bijuu. Imo Uzumaki = Uchiha = Senju because transmigrants represent the full extent of the clans power and they've always been equal.
