Naruto have no training with his RM so him getting use to it in battle while also doing more damage against Kaguya shows his superiory by your logic. I can use your argument against you since it doesn't say or show he can use in on a non-Chakra made creature so you saying otherwise is pure speculation. If you call those wins for Sasuke then that's just sad that he needs Naruto to hold back, be weakened, or have others save him from Naruto. You just making Sasuke look bad by saying he have 4-0 wins when it's only 1-0 which stills puts him on top but without plot helping him.
With that logic Sakura neg diff Sasuke when she had the kunai at his back but spared him so by your logic Sakura>Sasuke last arc huh? A win is a win right?
Sasuke already put Naruto above him when it was BM/BSM and EMS

and that's Naruto at about less than halve his power since Yang Kurama was out and he had to borrow some from Yin Kurama then gave a ton of chakra to the Alliance with Minato. So Let's add their other powerups. Sasuke got Hashirama's DNA that boost stamina, the little chakra Hashirama had left, a jutsu that Hashirama said would work on Madara, and the Sage's Yin chakra that gave him the Rinnegan. Naruto have Yin Kurama who can fully recharge his chakra, the abilities granted to him by the other 8 Bijuus, and the Sage's Yang chakra that gave him the truth seeking balls that we've seen block extremely powerful attacks and negate ninjutsus. Add all of that up and Naruto is overall stronger since Sasuke was jealous of only half or lower of Naruto's overall power.
