Nagato didn't have anything unique to himself when it came to the Rinnegan. Obito even used the former Jinchuriki to make his own 6 Paths of Pain. Hagoromo was called the Sage of Six Paths for a reason.

Sasuke's displayed the ability to use at least... Deva and Preta. A lot of the powers from the six paths overlap with his existing powers though. Why use Asura Path to make your body into weapons and armor when you have a Susanoo? He's already got 2 summon contracts prior to gaining the Rinnegan, so animal path is horizontal growth at best. Naraka and Human Paths were poorly explained and stupid even when relevant.

Seems to me like he assimilated the cool stuff into his skill-set and just doesn't use the rinne abilities that don't compliment his fighting style.
