I'm a fan of "use what works". I have products from Adam's, Chemical Guys, Meguiars, and others in my arsenal. I agree that Adam's is not the cheapest, but their presence here has made it easy to find out info about their products and they are always there to offer advice. I used to use Meguiars Hyper dressing on my tires. I tried Adam's VRT and now won't use anything else. I've tried several car shampoos and Adam's is as good as any other I've tried. I still love my Meguiars Ultimate Spray wax and use it after every wash. It also works on glass, leather and interior trim. It literally is an all purpose protectant. I tried H20 guard and gloss. I see everyone that has used it loves it, but I have a hard time with it streaking. That doesn't mean it isn't a great product. It simply means that not every product works for every person. Find what works for you. I would feel comfortable recommending Adam's to anyone because of their product support, ease of use, and product quality. While I also love Meguiars and Chemical Guys products, you'll be hard pressed to find the product support that Adam's offers. You get what you pay for. Sometimes that added cost is for more than the product (ie support and customer service).
