I would take the eyes, And I'm not being a fanboy or girl like everyone else, I'm going to give you a FULL explanation why. You see, I could always choose the body, but the eyes contain more unique powers of it's own. Such as the copy movement abilities of the sharingan, the dojutsu techniques of the Mangekyo and Eternal Mangekyo Sharingan. The seven path techniques of the Rinnegan which also allows you the mastery of the five nature types. There's even that unique spiral eye the elder son got from the sage. Now with the body, you get Immense chakra, longevity, massive strength, basically everything a senju has. I actually need to do more research with the "body" power. So let me put it this way, I would take the eyes, because I could always make my own body strong enough to witstand its power and to f1n1x saying "your body wouldn't be able to stand the eyes if you were to choose the eyes", that isn't neccisarily true. Look at the elder son of the sage, right there he inherited the sage's eyes and battled his younger brother. Look at the entire fu*king uchiha clan, their decendents of the sage's son, which means they are also the sage's decendents as well. They look like they're doing just fine with their eyes. Look at Madara freaking Uchiha, WE ALL KNOW his situation. So your body CAN witstand the eyes. Nobody never said you COULDN'T be an uchiha or something.
