I usually try to stay away from sound quality disputes, but PT Mix with 888/24 gave me great results in the late ninety's and contrary to what the OP stated it is not crap. I think that engineering {with any equipment that meets pro specs} trumps over gear. I remember about one audio test I posted at a Gearslutz thread, where 2 audio clips: one, a famous artist mastered by a well known ME, and the other, the same recording but remastered by me and processed with a PT Mix and the 888/24 to make my point more poignant.
The whole point to the test was to prove that with narrow band compression, it was easy to correct with certain amount of precision and less signal degradation, any frequency anomalies found in mixes/masters. Needless to say that everyone got it wrong. After their A/B review, no one was able to hear the frequencies that I had corrected. Instead, they all agreed that the original master recording sounded overall better and that my clip had actually "degraded the quality of the master".
The problem they encountered, at the end of this hearing exercise, was that the clip they believed was the "original" recording was actually MY sample master and not the other way around. Then, I was accused by some of rigging the test to make myself look right. Thank God that as a precaution prior to posting the test thread itself, I had given the results to the moderator Jay {the only stand up moderator at that mastering forum}.
To me it was interesting to discover how much poor/false information really runs through web forums, especially in regards to gear or its capabilities. But, the most telling aspect was to discover how many people come to Gearslutz to make blanket statements and to argue over things when they themselves can't even hear OBVIOUS changes in sound quality.
So my final thought is, if it works for you, use it, and try to stay away from sound quality discussions on most gear unless you have irrefutable proof to the contrary {A/B samples usually}.
