From behind the trigger I can't tell any difference between Unique and Universal. They both shoot the same and leave about the same amount of residue on the bench. I hardly ever start with a clean handgun so I can't comment on how the two compare in that regard.
I couldn't get Universal to meter well with my Lyman 55, Redding Model 3, or Lee Perfect powder measure with charges in the 5.5gr range. I picked up a RCBS Quick Change powder measure and can report that it meters charges of Universal as low as 4.5gr very well using the small metering assembly. With the RCBS QC I see +/- 0.05gr variance where the other measures gave me +/- 0.15gr variance.
