Good thread with strong points but in reality Uchihas are not that strong and here are reasons :
1. As Bobito said Sharingan is rare for Uchiha so majority of them didn't even manifest it.
2. Kishi clearly explained in databook that Sharingan can only memorise jutsu not give user ability to use memorised jutsu. So word copy is not really proper word translators used for this Sharingan ability.
3. Chakra insight is not as deep as byakugan and lets be honest its in 95 % situations useless ability it doesn't give you anything offensive or defensive just better understanding that can be useful in some situations
4. Precognition works only for taijutsu you can´t predict which ninjutsu is going to be used.
5. In war era we only had 2 MS users.
6. Even without Hashirama, Senju would still be stronger than Uchiha ( If we exclude Madara)
Tobirama already defeated Izuna second strongest Uchiha and given the fact no one else had MS its safe to say no other Uchiha can even match Tobirama with his FTG, clones , Edo army and OP water style that directly counter Uchiha fire style.
So in conclusion in order to really be relevant force on battlefield Uchiha needs MS and in war era there were only 2 of them while on other side they were 2 relevant Senju .
