Digital BW, The Print

Using Epson color pigments with 2200 I've had only one clog in several
years.. three weeks of sitting "on," no problems ...works great for
B&W with QTR...

HOWEVER  MIS UT7 in another 2200 clogs between sessions after sitting
"on" or "off" for a week. Usually OK just sitting for a day or two.
It's easy to unclog (one or two cycles), but is Piezo ink less of a
clog hassle?
 
Does one or the other look better on some typical fine paper, such as HPR?

Is one or the other easier to control when printing? 

Does one seem to dry faster than the other AFTER printing? 

I have the impression that MIS UT7 dries faster than 2200 Epson
color...your experience? What about Piezo?
