QTR-Quadtone RIP

I've noticed the comments about QTR vs. Image Print. Has anyone done
a 
comparison between the Windows version of IJC and QTR? I presently
use 
the OSX version of QTR but will probably be switching over to the 
Windows version. Just curious. It seems that one of the things going 
for IJC is possibly an easier interface for those not inclined to get 
into the guts of linearization. You pay a bit more for IJC and
I'm not 
sure how currant they can be with adding printers. I'm not sure.
I'd 
like to hear. Are the profiles for IJC more " neutral" over
the tonal 
range? A complaint from someone about QTR and the 2200.
