If DB stats are any indication Hiashi and Hizashi should be on par, w/ Hizashi being physically stronger. Though idk of Hizashi knows Rotation, probably does. Fugaku on the other hand only has the following that give us an idea of his power:
-Head of Uchiha.
-Has a matured Sharingan.
If Fugaku's power was anything like it is in the ItachI Shinden novel and anime, then he'd beat Hizashi comfortably.
