Richard, maybe you missed my last post of the last page or sorry I have not been clear : I knew PS before and as I have a simple post processing, and PS does it well, I just kept it.
I never really tried DPP, since the (beta at first) camera profiles have been released, the WB comes out almost perfect each time, so I stopped looking for other softwares.
I tried Lightroom and Aperture once and was not at all satisfied, WB was not better but noise/sharpening was worse. I gave up.
But hey, any body can go his own way, I fully understand people that are happy with DPP or NX !
