Sasuke is at somewhat of a disadvantage when it comes to his new visual jutsu. That is to say that he really doesn't know what his new eye is capable of. In other words, Sasuke can likely do what Kaguya and the Rinnegan users could do (or at least different versions of what they can do), but just doesn't know what that is or how they work.
In the recent chapters, it seems that Sasuke is learning what Kaguya is capable of, and I would expect him to pull out some new techniques in the next few issues.
