I use C1 90 percent of the time, and the much improved DPP about 10 percent of the time (it's really a LOT better than it used to be though).
I've found that for macro/closeup images, and images that don't require a large dynamic range, DPP can really pull out that micro detail. I know what Shirozina means.
On the other hand, I can't live without C1. The detail, the color, the seemingly extended dynamic range that it provides for my files, is incredible compared to everything else I've tried. I always, always, always go back to C1. I wonder what they'll do with version 4.
Also, there are files that would've been fine in DPP, but then they exhibit the stair stepping, and I'm off to process in C1, and everything is fine.
DPP has a nice grain structure though, and I like the color noise reduction (they finally included it in the later versions), and you can also remove color noise from JPGs and TIFFs, so no need for an extra noise reduction program.
I suppose it's best that we all have at least 2 RAW converters to work with, but that's the beauty of RAW. We can convert our files over and over again with a million programs without screwing anything up.
