We've had this discussion before. Naruto uses SPSM. Although since he uses it with the cloak, he technically also uses Kurama mode.

Note that when Naruto first uses SPSM, it's just the eyes without pigmentation. TSB's are gained when he engages the black underbody cloak. However, he doesn't have the other biju anymore, he used that up, so his epilogue cloak is gold again (Kurama's color) and so he doesn't have TSB's anymore either. (alternatively: he used up the TSB's against sasuke).

The databooks also show pictures of Naruto with and without cloak next to SPSM, so it seems the distinction isn't made (that is, the ability to manifest a chakra cloak is part of SPSM).

Combining this, anytime naruto has cross pupils without pigment, that's SPSM, regardless of whether he uses a cloak or not.
