The Uchiha Clan; the only clan in the entire manga with a proper myth created for their eyes. They work in tandem with their clan's ethos, their culture, and their history. That is all enmeshed within the clan created in the manga. None of the other clans even come close to this level of created history that works so closely with their abilities.
The Hyugas were the only one with political aspects going for them, but that had nothing to do with Byakugan. The other clans are practically worthless and I cannot think of any clan so flimsy, thinly imagined, and pointless as the Senjus. So, why would I be tired of the Uchihas?
