Man I had to delete and re post after reading your whole thread. The senju where equal to the uchiha. At the time of war the uchiha had no more feats or notable members than the senju(both had 2) ms and susanoo where the Uchihas best feats at the time, and so far we know of only mads that had susanoo. Tobirama had his suiton and ftg... and really? Only with ftg? He created the jutsu why wouldn't he use it? That's weird reasoning. And we already know hashis arsenal...It's easy to see that tobirama=izuna and madara almost =hashi and the rest of the members of each clan where pretty much fodder. By the time the uchiha where even a threat to konoha guess what, the senju weren't around anymore, bar tsuna. So if we're talking war period, it's hard to say their overhyped when there wasn't much shown on the uchiha side at the time either
