Uzumaki. The longevity and incredible life force are reason enough. Massive amounts of chakra? Check. You're basically the best body package (don't get the wrong meaning) alongside Senjus. Plus, learn Sage Mode and a few neat and strong ninjutsus, KKGs if you're lucky, and genjutsus to accompany SM power enhancement and you're basically boss. Have the added bonus of Fuinjutsu if you want.
Hyugas are pretty weak and limited in power and development, and in terms of what they are capable of, comparatively.
It depends. Do the Uzumaki get wiped out later in this scenario? and am I main or branch hyuga..
I don't think this question is relevant to history or plot. It might just be out powers, presumably.
