Kishi says that they are equal. Sasuke has Eternal Mangekyou Sharingan and fancier Rinnegan and possibly also Hashirama cells. Naruto has Six Paths Sage Mode + Kurama and possibly still some leftover chakras of the other Tailed Beasts, also Hashirama's cells. Not to mention during the 4th war Sasuke was already said to have mastery over his Rinnegan on Hagoromo's level and many years have passed since.
