Hey Phil:
I'm a mac guy, go figure from my signature!
I use MOTU stuff exclusively, not because there's not something better, but because it's not time for me to upgrade yet. After 10 years of public school music teaching, and a bit at a university, I got tired, not only of the administration, but also of the shoebox wintel world.
I use DP3.1, upgrading soon, and Mosaic 4.something. Haven't used any 'VI's' since "Studio Session" from the late 80's. Still have the software, but I don't have a Mac it will run on!
