Fail prior to the latest chapter naruto was stronger but since sasuke has control over the majority portion of the bijuu and naruto only has half the kyuubi and pieces of the rest then yes sasuke is more powerful than naruto.
Naruto cannot combat 9 bijuu and rinne sasuke with shared vision and rinne techs.
Naruto has clones and frs senpou bijuu traits which would get tanked by the bijuu and or st or preta path, naruto can do nothing as of now but plead with sasuke to stop.
Explain why you think naruto is stronger???
Um explain how sasuke is he isn't using them in the fight at all he already sealed them didn't naruto take on multiple tailed beasts just in his kurama link mode? Yes he did
And he is much more power then that now he has the sages power and portions of the tailed beasts
And not to mention he has the truth seeking balls
Basically naruto has all the abilities of the tailed beasts their power combined the sages power giving him the truth seeking balls giving him every chakra nature and possibly able to shape them into weapons and kaguya was shown to combine her natures having wood style
We still don't know his full extents nice try
