The reason I don't use it with NX2 is because it doesn't seem as controllable as Ps, you can't use layers or other plugins for example, so I can't give a true side by side comparison. But, I don't have a problem with noise in Ps. The settings I use all the time for
Tonal Contrast are 12, 12, 12 and 2. Then I back the layers opacity down to between 50% to 75% It gives a subtle boost to the photo....
