Digital BW, The Print

Has anyone made a direct comparison (preferably of the same image on the 
same paper) of UT-2 versus ImagePrint or QTR w. Ultrachrome inks and, if so, 
what are your conclusions?  What differences (if any) do you see?  (You don't 
need to have printed it yourself -- your impressions would be useful if you've 
held a QTR or ImagePrint print in your hand next to a UT-2 print).

I've run a search and can't find any threads from anyone who has done a 
direct comparison themselves.
