Ever since naruto came back or was still trainning in the mountains people have been comparing him to other ninja of legends. People like J-man, yondami, kakashi blabla and they say oh naruto can't win because he isn't smart enough or not enough experience.
Well IMO power is the most important factor in the world of naruto. Take for example the (SMARTEST) people in the show, J-man and Oro. They inherited the title sanin for a reason. Well wht did that do against a four tailed naruto. Both were severly wounded or darined out. And oro was a former AK memeber.
As long as the gap in power is great enough naruto can win. I believe that the only time that smartness is worth anything in naruto is when the fighters are close enough in power. i.e a sanin battle, (oro vs the third, oro vs j-man, tsunade) or jouni battles
If you want to think of some who can fight a naruto with clone mastery and rasengan, then fight against a sage naruto then again an uncontrolable demon naruto i'm open to all suggestions.
sry if this thread sound angry cuz it is but i just felt i had to say it.
