Although they were said to be equal. Man for man im sure the uchiha were stronger. Anyway i agree with what narutopedia says because that makes the most sense.And the Uchiha remained?! Not good enough... after all they're meant to BOTH be powerful rival clans... If that was the case... we can see who is the strongest of the two... But I've always wanted to see them as equal... but after seeing the power of Madara Sama and I got over my moment of fanboy hype... I can't see how Senju could ever compete!!! I'm not happy about it! xD
This is further evident in the fact that hashirama a senju married an uzumaki. Therefore they mostly married outside their clan unlike the uchiha and hyugan
