It's important to compare the same actual coffee decaf and regular. If you do this, you will find that the decaffeination process does ding the quality a little, but not by too much (maybe 2.5 points out of 100). As far as I can tell, the different processes are equally good.
Also, decaf needs to be roasted to a lower finishing temperature with lower drum or environment temperatures, and with faster roast times (this is especially true of the water process beans); which for most roast setups means lowered batch sizes.
Some of our favorite roasters do all this, but nobody else would dream of it. Given all these ways decaf can be screwed up, the large majority of it ready to buy is completely undrinkable.
