IMHO, it really comes down to whether you want a fixed tone inkset or a 
variable tone inkset.

The main reason to use the UT7 set is that you can vary the tone to 
suit, within reason. The main disadvantage is the possibility of 
differential fading over time pushing the print's tone warmer or cooler 
than you intended.

The K7 inkset has several advantages. The seven dilutions can give 
smoother tonal transitions than a four dilution set (the UT7 set is 
essentially two quadtone sets - a cool set and a warm set with a common 
black). Since the K7 set is a set of dilutions of a common black, 
tonality will be the same as the inks age. There should be no 
differential fading over time that will change the color of the print. 
You don't have to spend time and resources (test prints) picking a tone 
- the tone is fixed. Because the tone of the ink is fixed, you can vary 
the tone of the print by varying the tone of the paper.

I'm sure if I missed any, others in the group will chime in ;-)

Happy Holidays!
