A few things to keep in mind...
First, remember that Wolfgang is a house brand. It's part of PBMG - the parent company of AG. So the brand gets lots of promo. That doesn't mean that it's the best. It just means that it gets lots of buzz.
Second, many of the people who rave about any product have never had any experience with any other premium-grade product. So they blather on about how great a product is, but that's all they've tried or they only have experience with some OTC garbage from their local auto parts store. (You can get some decent stuff at auto parts stores IF you know what to look for.).
Third, do NOT buy brand; buy individual products! Almost all companies in ANY industry make their name with one or a few good products. Then they invest their profits in brand-expansion products. For example...
Zaino started with very good sealants. Then they added a polish, clay, leather treatment, tire dressing, plastic cleaners, etc. Are these new products unique and great? IMO, no. They are good products, but there are other brands of these addon products that are as good or better. I use Menzerna polishes, CarPro PERL, and UTTG, which are better than their Zaino counterparts, IMO. And I'm testing Zaino Z5/Z2 Pro against UPGP and 4*UPP; results are mixed so far.
The bottom line is that your list needs work. IMO, a good starting point is Corey's (Ceedog) Best Of list:
Best Of - AUTO DETAILING AND CAR CARE PRODUCT SPECIALIST. You may change your mind in the future as you gain more experience, but that list is a GREAT starting point.
Good luck with your choices.

Dan.
