Let's put this to bed
The perfect example to show who is stronger Sasuke fire ball vs Itachi fireball
Genjutsu fight
Taijutsu clash
Itachi was overpowered
In all to the point he used ms and clones
That's hebi Sasuke
Logically we can assume a healthy itachi is stronger than that similar to edo Itachi but a mentally healthy ms Sasuke again will be stronger
Itachi can still beat Sasuke even though sasuke is stronger
