How is it that people think that the Hyuuga is lower than the Uzumaki? Thier clan is literally featless. You cant just assume how powerful they are based on a few sealing techniques that were not even used by them in the first place.
Being wiped out does not prove their power either, being that they were all practically killed. The Hyuuga/Uchiha/Senju were widely known as the most powerful clans in existence.
Most other clans were mostly very feared by other nations, but not to the extent of the above three clans.
