Ninjutsu and genjutsu. Either can be used physically through the body or spiritually through the eyes, but are opposites none the less.
And just like the uchiha, the uzumaki has members that develop chakra physically that is used to suppress and control the kyuubi while the uchiha have members who develop chakra spiritually (i.e. the SG) that suppresses and controls the kyuubi.
IMO, this implies that madara wasnt telling the full story and the uzumaki are the true original brother of the uchiha from the sage. The brother who received the RG while the uchiha received the SG (both gained half of the sages power). and the senju are most likely just power split from the uchiha after a battle between the brothers for control due to the SG dark nature. This could explain why the SG is so much weaker then the RG at base and needs two extra levels to equal. As well as how tobi can create a MS level physical jutsu with a mere basic SG due to him using a senju body (hashis body clone of white zetsu).
