This is a comparison for an image that I consider a keeper in my book. It's a female Merlin, we had fast moving clouds when photographing her, and this frame was underexposed by 1/2 stops. I converted this file with DPP 4.15 using the exact setting explained in my guide and then tried ti match it with ACR. Below is what I got. Despite what is was said a few times in this thread, it doesn't take fiddling with sliders etc. to get a good output from DPP. In fact I just made the adjustment once then copy-pasted to a bunch of images.
Shot with Canon 1D-X and 600 II + 1.4X III. ISO 2000. 1/2000sec at f/5.6 hand held.
The DPP conversion is sharp and clean, no visible noise and the colors/WB comes out right on the money with no adjustment. With ACR, same file looks softer and grainier. The colors are off too (dull and lacking). No matter what you do, you cannot match the DPP's sharp clean look in ACR, more sharpening will make it even noisier and less sharpening makes it softer. You may be able to match the colors but you have spend a few minutes fiddling with the adjustments.
And this is the final file, converted with DPP, re-sized and sharpened for web in PS
I hope this thread was instructive
