Four Star UPP on black paint?

Is it better in looks than Menzerna PL or DG 601/105 on black paint? I ask because there was rave reviews about Four Star UPP a few years back on this site on the search button. It's very pricey at the detailing store I can purchase it from (Canada) and was wondering if it was worth it and also what detailing spray would be compatible with it after washes? Thank-you.

If you already have PL no need to open another bottle

No, I use DG 601/501 then top with DG 601/105 and once a month or so DG AW . I was just wondering if Four Star UPP OR Menzerna PL made black look better (DEEPER and SHINIER) than what I am already using from DG. Thanks.
