In the final fight between the two, Naruto has what appears to be his normal Kyuubi chakra form, whilst Sasuke obtains a Tailed Beast Susano'o by harnessing their chakra. It differs in appearance mainly by the chakra in the middle of it, but one can see that it possess's an open armour structure in comparison to the standard sealed form of a Perfect Susano'o.

When Naruto and Sasuke combine forms against Obito, the Kyuubi is Naruto's form, and he does not obtain all of the other tailed beast powers until after Madara's revival. When the two fuse here, the resulting form is basically a purple Kurama, fully closed off. In the Boruto movie, when Sasuke and Naruto fuse temporarily, Naruto's form appears to be the same, however the surrounding armour that Sasuke makes is closer in appearance to the Susano'o used at the Final Valley.

From this, would you think that Naruto's Kyuubi mode actually uses some amount of the Tailed Beast's power, which is why Sasuke's Susano'o took the Tailed Beast Susano'o form (this would also mean that Naruto was using SPSM in the movie, I think, though the skin colour being gold may mean he is not) or can Sasuke just shape his Susano'o differently?
