Digital BW, The Print

I am using Epson enhanced matte paper on a 2200 machine.
Given that there could be so many variables in terms of curves
or RIP's utilized, I understand that my question would be difficult
to answer but here it is:
Is there a difference between MIS UT and UT7 on EEM in terms of dmax ?
If so, which one is better ?
