Hmmm it's hard to say I mean when it comes to jutsu we have seen that that naruto aids sasukes. so naruto is going to have to use all rasengans but rasenshuriken. To me it's hard to decide because we know they both are hiding something up their sleeves. I honestly can't figure this one out.
KM Naruto? EMS Sasuke beats him mid-diff.....do to the simple fact that KM Naruto doesn't have any jutsu that would destroy his Final Susanoo and also the fact Sasuke can spam Enton from every area and even defend himself with it.....too much for KM Naruto
