QTR-Quadtone RIP

My main printer is the 2200 with OEM inks and if I understand things
correctly printing with QTR uses the black and light black inks with
maybe a touch of color ink for toning.

I also have an Epson 1160 that I'm considering dedicating to B&W with
MIS UT inks. The 1160 uses black and 3 colors normally and I
understand the UT inks will be black, light black and a couple of toners.

Will I gain anything in quality by using the 1160 with UT inks over
the 2200 with UC inks?  They both sound like 2 inks and two toners.

I must keep the 2200 as is with the OEM inks so dedicating it is not
an option.
