Privatebydesign has been wanting to be shown with examples why I and others use DxO for RAW noise reduction. I use it for that and also as a RAW converter as it gets me the most detail than my limited skills can get with DPP and PS, and very quickly too. Here is an image of a bellbird taken in New Zealand by wife using a 5DSR and 100-400mm II at close range. It was deep in the canopy, illuminated by green light, taken at iso 6400 pushed through 1.6ev in post-processing, equivalent to a shot at iso 19000. THe top 3 shots are processed respectively in DPP, PS and DxO prime. To get them on the site they are reduced from 50Mpx to 6Mpx. At this reduction, they all look rather good, and show that the 5DSR is fine at high iso. But, the likes of us birders crop like mad. So, below, I have the centre section of each at cropped at 100% at full resolution. Again, DPP, PS and DxO prime. Here, we can see clearly that the bottom one from DxO has the sharpest detail and in the shadows on the left the least noise. I really didn't want to do this as someone will want me to play around more with the sliders in PS and DPP, and I am not going to do that as I have spent enough time in the past doing so and my skills set is not improving. If you don't work at high iso and don't crop, you won't see much advantage, but if you do, there is a great one. I haven't used Topaz etc for ages and can't comment on those.
Edit - I have added the unsharpened uncorrected at the very bottom for comparison.
