Can we all take a moment to acknowledge the straight grind sasuke went through in his own right he made himself the main anti-hero. Binge fights narutians! Orochimaru, Back to back deidara then slight pause like three weeks i think, itachi, 5 kages, danzo, kakashi, strong enough chidori to make stalemate with a rasegannwhich as we remember in part one it wasn't close to being as strong. Sasuke also did all of this while adjusting to mangekyou pain. Must have been severely intense if he lost his vision almost after a few weeks when itachi had his for years. Because sasuke is able to venture out on his own with his powers meaning he can go to different dimensions and pose a powerful threat to their beings means he can steady progress because more competition and learning. Boruto will benefit majorly and may train in different dimensions to make his own original jutsu. Sasuke is a genius in every way so how he portrays his teachings will make his dojutsu usage and og jutsu very unique and stunning
