Moon level+ (Received half of Hagoromo Ōtsutsuki's power alongside Sasuke. Momentarily matched Kaguya's Gentle Fist with his chakra arms and sliced her arm off with a chakra claw. His Rasenshuriken was able to completely obliterate Madara's Chibaku Tensei, creating immense blasts), far higher with Six Paths Kurama Avatar).
Received half of Hagoromo's power = Hagormo Six Paths Chakra, alongside Sasuke.
You didn't explain to me why Sasuke awakened his Rinnegan so immediately compared to Madara, who took decades to awaken despite having the same Hashirama's cells. Sasuke (Has Indra chakra) got Hashirama's cell and he awakened instantly, Madara (Also has Indra chakra) and got Hashirama's cells, but it took him near-death to awaken? Why? It is because Sasuke is not the same as Madara. What Sasuke gained is Six Path powers and what Madara gained is only Hashirama's cells.
Sasuke says both him and Naruto have Six Path Power. Having Rinnegan =/= Having Six Paths Powers, so why Sasuke said he has Six Paths power? Madara didn't have Six Path powers or chakra at all when he got Rinnegan but until he absorbs Shinju. That's why he said, "So, this is Sage of Six Paths power". So why did Sasuke say he has Six Path powers alongside Naruto? It is because he received Six Path Chakras from Hagoromo, Kabuto healed him somehow also made him meet Hagoromo and then he received half of his power.

When Hagoromo took it back, Sasuke kept the rinnegan.
