Kyuubi: his father and mother give it him.
Sharingan: booldline.
And let me ask you all this question....is the Sharingan a living thing? while Kurama on the other hand is a living thing.
Ok yes Kurama is a living thing but Sasuke got his power from another source just like Naruto got his power from another source.
Sasuke was made to take the eyes from his brother just like Naruto was the only one who is able to house Kurama.
Yes there are similarities but how Naruto has mastered his power far exceeds anything Sasuke is doing right now. Sasuke's Amaterasu was unlocked by his brother in hope he would be better than him. Sasuke needed his brothers eyes to even get ahead in that situation while also gaining a great power boost. Even then with the EMS Sasuke was of no use when both Itachi and Sasuke were fighting Kabuto.
Naruto on the other hand have been dealing with his power all of his life and is much more mature in how he uses it. Now I could say that Naruto is more powerful than him, which he is, but that is irrelevant when you look at how much more mature Naruto is with his power. Naruto has much more control over his power and has brought it to lengths that Sasuke right now would need some assistance from Senju DNA in order to attain the Rinnegan. I only say that because of when I seen him fuse both the SM and Kyuubi energy and now since he has BM that potential right there would be so much greater.
So like the OP has said everything that Naruto has is his power because not only was he with Kurama in the womb but he inherited by fate or just because he was the only other Uzamaki who could ever house Kurama again who knows. But the point is he has had it forever and has been fighting a literal demon not something dealing with emotions or thinning bloodline from Rikudo. He has trained, worked hard, appreciated, and acknowledged his responsibility for such power that was given to him by his father and why it was given to him.
IMO Naruto has made every power he has his own and no one can dispute that because he has mastered all of them like it was second nature.
