i say nagatoss because we did not see tobis jinchurikiss rinnegan powers ... only share vision. If i saw tobis pains rinnegan power i would say tobis pains>nagatos
this ain't a stupid question.. what so ever.. people who are underestimating their opponents are just stupid.. nuff said.. u can't say winner just by cuz tobi has jinchurikis as paths, which nagato+akatsuki have alrdy beated (when they were alive..) tobi just reanimated them.. but after lil thinking i dunno who would win..
