In most cases where there is only light noise in the picture (i.e. no banding noise) I use DPP's noise reduction functions. It does a decent job if you use it very moderately. I never push the luminance NR slider higher than 5 because it is a bit heavy handed and you lose quite a lot of detail. For noisier pictures I use NIK Dfine 2 (available as stand alone app or as plug-in for PS, LR, and Aperture). Dfine has a lot more options than DPP. For instance it lets you define where in the picture noise is measured. It is also rather good in retaining detail even if you have to apply stronger luminance NR. Dfine also lets you tackle banding noise but I am not too happy with that function: although it removes (most) of the banding patterns it tends to introduce its own artifacts, especially along contrasty edges. But all in all it is the best NR application I ever used.
