Opinions?

So I have been looking and I was thinking about getting...powerlock, PO85RD, PO106FA, and Prima Swirl...that all sound alright? Should I add Super Intensive to the list or will Prima Swirl be enough? How often would someone actually have a car bad enough to use Super Intensive or even Power Gloss?! I figure the Prima Swirl should be enough since everyone says it is similar to Power Finish which isn't much difference in cut compared to Super Intensive, right? Thanks for the help!
