Using the duotone process (at least as I know it) in PS in 
combination with a printer like the 2100/2200 needs a color or "tri-
tone" -low gamut inkset like UT3D plus icc-profiling (PrintFixPro is 
often advocated for this in the DBWTP group). The advantage of this 
would be to have a monitor soft-proofing capability.

For me, the advantage of the QTR approach is that you have absolutely 
great control over the ink choice (any inkset can be supported) and 
curves (e.g. you can to great extent to get the ultimate Dmax or 
smoothness). 

Furhtermore, the workflow is just different and that's very much a 
matter of taste. I prefer to split my attention to first focus myself 
getting the best possible B&W in PS and only then add the toning 
during printing.
