I used QSuite yesterday and was able to answer my own questions.
QSuite has the equivalent of the stand-alone QScan and Booktype Management software rolled into one application. It also has a way to turn WOPC on and off, and also provides a way to turn Simulation mode on so that you could try "burning" at different speeds without really writing to the disk. (You don't have to turn simulation mode on in your burning software, QSuite turns off burning in the drive instead - pretty cool).
I ran QScan and QSuite on the same disks and I determined that they both give you virtually the same graph, except that QSuite has the ability to test all the way to the outer edge of the disk because you can configure the starting and ending LBA (they are fixed in QScan).
Overall, I agree that QSuite is better than QScan alone.
