C1 3.6.x and later are the king of chroma noise removal, IMO. I think version C14 is terrible with color noise, and I have to use other software to remove it from the converted 16 bit TIFFs, if I were to use version 4.
I think Lightroom is tied, or second best with color noise removal and control. Plus, it just gives you clean files, no matter what file you're processing, however, sometimes you need to add in a fine edged sharpen after converted from LR, where in C14, it gives you the control for the radius, amount, threshold, etc, more so than LR does.
