I spoke to Kishi's cousin and it's unanimous. Naruto as an adult still has the same RSM from the war(bijuu kkg, tsb, comprehension, etc.) however in efforts to change the history of tailed beats being used for power he opts not to call for their power unless it's a truly dire situation like a 10 tails jinchuuriki or a OP ootsusuki (momoshiki was not one) only with the elements of all bijuu can his skin remain regular instead of glowing like the rest of his cloak but with RSM with just Kurama his skin glows too but still no sage mode eye shadow.
The only exception to no tailed beast is Kurama of course, who is entirely inside Naruto and has integrated his self into Naruto's chakra and fighting style, also developed a true friendship with. In contrast to Naruto only sympathizing with the rest of the beasts. Not to mention he has 100% Kurama now and full sage mode mastery. He trashed Toneri who had an equivalent to RSM witch just BSM.
So all in all we have yet to see a full power Naruto or Sasuke with mastery of Tomoe Rinnegan.
It probably would be a draw so let's end this fued of Naruto >< Sasuke.
