I haven't used either application so I couldn't tell you. Most likely the software algorithms can't take advantage of everything raw files have to offer because each manufacturer releases their own, proprietary raw file codecs. This is why it takes Adobe a few days or weeks to support new cameras when they come out... Adobe reverse-engineers the .NEF codec so that ACR and Photoshop can converse with those files. JPG, on the other, hand, is an open standard. Once I fully appreciated the flexibility of working with an uncompressed 14-bit raw file, in 16-bit mode in ACR/Photoshop, I couldn't go back to shooting JPG. Not that there's anything wrong with JPG, it's fine for what it is but at the same time let's be frank: JPG is, inescapably, IS a lossy, compressed, 8-bit format and there's no getting away from that. Shooting any modern DSLR in JPG is, in my opinion, castrating the camera. Again, nothing wrong with JPG, it's great for what it is; but if you want to unleash the full potential of your DSLR, you need to be shooting in raw, and processing in 16-mode to take advantage of it.
Sorry if that came off as an anti-JPG rant... It wasn't meant to.
