So I have been doing some experience with both UPP and EX, I like both products alot. They seem to be similar with subtle differences, the UPP seems to have more gloss and the EX more depth.
Using QD's on both of these I have found that Clearkote's Quikshine is great on EX, it adds some gloss. On UPP I like Poorboy's QD+ adds a slight amount of depth.
