The Senju and Uzumaki Clans are two separate clans though, and if anything the Uzumaki branched off from the Senju. The Senju Clan may not have any specific defining traits but it was the most powerful clan in the world only rivaled by the might of the Uchiha Clan. They were prodigious in all forms of Shinobi combat, they were consistently hyped up and had superior portrayal to the Uzumaki Clan, and if the Uzumaki branched off from them and they're both descendants of Asura Otsutsuki who possessed his father's "body" then the Senju and Uzumaki likely both possessed the same abilities but the Senju were not known for it because they died very young in combat against the Uchiha all the time, and vice versa. This would be fitting with the clashing "body" and "eyes" theme anyway and it would make sense for the Senju to have something special to combat an entire clan of Sharingan-wielders raised in warring times.
