kinshiki was also beat by the 5 kage low diff so 5 kage > adult sasuke to you?

adult versions got much stronger than the teen versions but you need to understand how weakened they were, naruto gained an extra half of kurama and got better at taijutsu which is much stronger, but in the fight, naruto was at 50% anyway so the extra kurama doesn't matter

sasuke mastered the rinnegan but he now easily has less chakra than his teen self, it's literally a meme that sasuke runs out of chakra within one move, on top of that he even transported a lot of people which the chakra required scales with

you said rinnesharingan, not rinnegan, he has 3 rinnegan yes

obito also doesn't have a feat of being one shot by a base form naruto either you see
