Sorry, I misunderstood. But isn't this thread about power?
You aren't talking by manga facts either. And even your logical reasoning is non-existent unlike mine (below).
I'm talking by analysis and potential. In terms of ninjutsu, Uchihas are generally on par with the Senjus. Their signature chakra natures are also polar opposites i.e. Fire and Water. And presumably, they'll be equal in long to mid range combat. But the Uchihas are definitely superior in CQC to an average Senju owing to their Sharingan. Not many members awakened MS or learned SM, so let's keep it to a rarity. And Uchihas have powerful chakra while Senjus have larger reserves, so Uchihas have the edge initially in the battle because quantity of chakra is not that important then. So they can easily defeat Senjus earlier. More chances.
And just because Hyuga became the strongest after Uchiha died doesn't automatically mean the Uchiha became stronger when Senjus died. What the hell is this logic?
@bold False. Never did every Senju know all elements.
And Senjus were superior to the Uchihas during Warring States Period only due to any factor. That's what the manga tells us. The rest of the time, they were on par. But potentially, Uchihas are slightly superior, in general (through analysis).
Maybe there superiority during the Warring States Period was just a plot device along with Hashirama's superiority over Madara as well as Tobirama defeating Izuna which urged Madara to gain more power and get him to awaken the Rinnegan by feeling the need to obtain more power. Because if Madara was stronger than Hashirama, he'd never feel the need to obtain more power so he'd have never awakened the Rinnegan. And if Uchihas were stronger than Senjus, they'd never defect to the Senjus, which would never disappoint Madara, and Madara would never leave the village and fight Hashirama for supremacy, and would have never awakened the Rinnegan.
