Found this nice comparison of several of the common RAW converters out there. It uses a base RAW file from the Canon 5D Mk II. I will certainly try some of these others out. I went from using Bibble 4.9 to LR 2.2 and I have to say, Bibble seem to produce much more pleasing color tones with my Canon 30D RAW files. Needless to say, I'm not completely satisfied with LR
Here's the review of the different RAW converters such as Lightroom, ACR, Capture One by Phase One, Canon DPP, DxO Optics Pro, and Raw Therapee:
