OK, then I can say we find common language as we agree
For current manga I believe EMS Sasuke = BSM naruto but if Sasuke get Full size PS body as Madara then I believe he will be truly supperior until Naruto got Complete Kurama and then they could be equal once again. FInally Naruto could get full Kurama BSM which could put him above Sasuke... unless Sasuke get Sennin mode as well.
IMO: Hipothetical full Kurama BSM Naruto > Enton full PS Sasuke > Full kurama BM naruto = Full PS Sasuke > Half Kurama BSM Naruto = Half Size PS Sasuke(Current one) >= Half Kurama BM Naruto.
Just my guess, what do you think about it ?
