Senju. I like Wood Release Techniques and too regeneration abilities.
I could be peaceful alone living in the forest without annoying quarrel, war and troublesome foolish family,clan,rivalry.
I choose Uchiha so I can have Sharingan, Mangekyou Sharingan, Rinnengan. I can just take Hashirama DNA to make my body stronger like a Senju and even gain Mokuton and then learn Sage mode.
Sharingan is great since I can learn anything easy, mangekyou sharingan gives overpowered techniques and Rinnengan grants me the affinity of all basic element along with Yin and Yang element. I would no need to steel anyone eyes just gaining Senju DNA would stop the blindness.
Sarutobi. I have to be realist. Choosing an Uchiha or Hyuga is like getting a golden DNA ticket whom I knew few in real life -that can do nothing but being thankful about their inheritance= hahahahahahha-, and Sarutobis do have a good chakra pool, most of them seem able to manipulate more than 2 chakra natures and they´re incredibly loyal so it does paint a picture of my own old folks.
Added to the earlier, I know nothing deeply but know a lot about everything like those guys do about ninjutsu
Uzumaki jus off the strength that they had to be some serious badass MF's that genocide was committed to stop them and we see how powerful the last of their clan are. Nuff said
