Earlier in the thread, they said that the two original clans were uzumaki and hyuuga, and Kakashi said in the manga/anime that the uchiha descend from the hyuuga, Uzumaki have almost all of the senju traits - stamina, chakra, etc, yet the senju dont have all of the uzumaki's - Chakra with special properties, Kurama compatability, Fuinjutsu, etc. I think the Senju are actually descended from the Uzumakis, not the other way around. I think the same way about the Uchiha and Hyuuga, the uchiha were said in the story that they were descedned from Hyuuga, so i dont need to provide evidence for that. Overall I think uzumaki is better, and to add on, I think the reason that Hinata and Naruto have been paired togethe a couple times (Pain Battle, and during the fourth war when Naruto saved her, and again when Neji sacrificed himself) is because the Rikudo sennin was both Hyuuga and Uzumaki, not Senju and Uchiha who stemmed from Uzumaki and Hyuuga
