The design clearly indicates that it's an unfinished Rinne Sharingan (Rinnegan ripples and six Tomoe, compared to Sharingan's three and Rinne Sharingan's nine). The powers, however, show that it's a Mangekyou mixed with Rinnegan, as it's also purple.

Madara however seems to have lost his Mangekyou powers when it became a Rinnegan, whereas Sasuke got to keep it.

I also don't know why Sasuke has only one, as logic would dictate that a natural awakening would give him two, but i think it's to hammer home the point that he only has half the Sage's power.

It's not clear of Tengai Shinsei can truly be said to be a unique rinnegan jutsu, as it seems to just pull an asteroid from orbit using Deva Path. Sasuke's Spacetime ninjutsu also seems to be powered by his Mangekyou, not his Rinnegan (His Mangekyou retracted in Naruto gaiden) whereas his Amenotejikara is powered by his Rinnegan (he is forced to close the entire eye after a few uses).
