Except for the fact that both Naruto and Sasuke got Hagoromo's chakra.

With Sasuke, it awoke Rinnegan, since he has "the eyes".

With Naruto, it awoke Six Paths Senjutsu(in form of Six Paths Sage Mode), since he has "the body".

Rinnegan and Six Paths Senjutsu are the halves of Hagoromo's power, which he then shared with Sasuke and Naruto respectively.
