You may get better answers if you post in the 001 for windows forum. It's at
DUC 001 for Windows
There's also a MOTU forum at
UnicorNation MOTU forum
The problem is that there's no one that can really tell you what's best for you, except to use the stuff and decide yourself. Tough, I know. Obviously, all of us here love PT. At MOTU, they'll love Digital Performer. Personally I like both software, but prefer Digi I/O. What software does MOTU use on the PC? Digital Performer is 'Mac only' I believe.
