Here are the three blushes side by side. Nars Orgasm is on the left, Nyx Pinched in the center, and Nars Deep Throat on the right. In the picture, the Nyx blush looks closer in color to Deep Throat, and orgasm looks like it has a more reddish/gold tint.
Here are the three swatches. Orgasm on the left, Pinched in the center, and Deep Throat on the right. Orgasm and Pinched have very similar colors when applied to the skin, and Deep throat is lighter and not as pigmented. Orgasm has more shimmer, but when applied with a lighter hand it matched Pinched almost exactly.

I applied both blushes to my cheeks to see how they matched on my face. I put Nyx Pinched blush on one side and Nars Orgasm on the other, and I couldn't tell the difference between the two blushes.
Nars Orgasm Nyx Pinched
These are almost the exact same color on my skin. Both blushes apply nicely and are easy to blend in. I think Nars blushes are really long lasting so I was putting the Nyx blush to the test to see if it was too. I think this Nyx blush did last long on my skin as well, and for the great pricing it's great dupe for Orgasm if you don't want to spend $29 on a blush!!
