Marc, I'm glad you got good results from Cathy for your Canon.
At least for Epson, I've had better results from Andrew than from Cathy (or Dry Creek or IJA). The most noticeable difference is that Epson drivers have trouble differentiating details & gradations among green tones, sometimes reducing gradations of 'grass green' to mush. The profiles she made for me didn't fix this. Andrew's - presumably because they're based on more sample patches - seem to fix what Epson had broken.
Also more shadow detail, a little more saturation, & better skin tones, when printing the PhotoDisk target.
