How does gaiden show sasuke is stronger naruto soloed the shin army and sakura saved sasuke from getting killed yes naruto was stabbed but even kurama said that wasn't enough to kill him what makes u think sasuke is stronger?gaiden already shows that not-fullpowered sasuke > hokage nardo. and, the movies will shoot a lot of boruto and sasuke.
plus, kishi himself states they're now equal.
sorry to disappoint you but that aint happening. the denial tho.
