Interesting comparisons, and of course one shouldn't be surprised that different profiles produce different outcomes - especially between vendors the "base case" or "default" profiles will differ, again producing different results. As I've never yet processed a raw image that didn't need colour and luminosity adjustments, the more interesting issues for me are "which provides the better starting point", and "what are the criteria for defining a better starting point"? In addressing those questions, I would begin by casting aside any notion of scene-referred "colour accuracy" for anything but photographs made under very controlled conditions to reproduce known and required colour values.
