Not necessarily that is still unknown.
Naruto has all of the foxes chakra and could just destroy the rocks with a massive Gargantuan Rasenshuriken Barrage maybe thats his most powerful.
But the argument is about the 6 tails who does not have chibaku tensei. Still has no chance how about you argue HOW the 6 tails would win in your opinion instead of giving counter arguments to others points
a tailed beast bomb and current naruto is dead. rasengan is shape manipulation, rasenshuriken is nature and shape manipulation, rasenshuriken is stronger and whatever naruto has wont work as the six tailed naruto took an explosion of his own tailed beast bomb and was not scarred, check the battle between pain and six tailed naruto. how will he defend the tailed beast bomb?
