I can't believe that at this point in time we are still arguing Naruto having SPSM. the series itself has been vague about Naruto's and Sasuke's powers since the war, so i can't entirely blame people. A dozen or so threads on this have created a consensus on this board, but that doesn't mean everyone is aware of it.

As to Naruto having the other beast's chakra, i think that at this point if he still had it, he would've used it. His cloak design has become Kurama-like again, and various special powers like a Magnet Release or Boil release would've been extremely useful against Shin and Momoshiki respectively. I think we can attribute design differences to the fact that both Naruto and Sasuke have Six Paths power of their own.

The other argument is that it would also go against the promise that Naruto made to the beasts: That he would free them. They were only helping because they wanted to, and afterwards went their own way.
