Dude you need to chill out. One guys agreeing with you, and your cursing at him, the others just asking where the page that states it is, and your not showing him, you've said you've showed the page to people many times before so they would just shut up, so one would think you'd know the page by now, and it wouldn't be that hard to retrieve. Also theres nowhere in the manga that directly states that the Senju clan surpassed the Uchiha, it only states they were rivals, and equals to a point. It does however state that Hashirama defeated Madara. The Senju clan is the more level headed of the two though that's why even in the beginning Uchiha's themselves wanted Hashirama as a Hokage. You really don't know for sure who the stronger clan was. Just because one guy(Hashirama) surpassed the strongest in the Uchiha clan(Madara) doesn't mean that if both clans fought to the death that the Senju would come out on top. If that was the case then why were there such an abundance of Uchiha when the whole clan was massacred, and only a couple Senju. I'm not disagreeing that the Senju aren't stronger, in my opinion they probably were, but that no longer matters because both clans are pretty much history. Sasuke probably won't have any children, and deffinately not Obito, so seeing as how there the last of the Uchiha the clans pretty much done with. There may be some distant relatives that contain some Uchiha DNA that we don't know about, that are capable of awakening the sharingan, and there may be some distant relatives of the Senju since a lot of them copulated with Uzumaki's, and the Uzumaki spread out to every nation, but I doubt we'll hear about any of them.
