Ive said it before, but I believe Adams is an outstanding product for non-Autopians. If my grandfather were to use his line of products I'm sure he would be impressed with them, just as I was before I found Autopia. They provide very good results on a general consumer level, but we aren't general consumers ... we are enthusiast's.
When you come into the Autopian world though, there are products that do the job quicker and better. Adams products, IMHO, are not tailored for extreme enthusiast's like us, they are designed for people who either have a garaged show car or people who don't know better. I hate to say that about their products, but most car owners don't give 2 ***** about swirl marks nor do they have any idea how to fix them. So for them, the Adams stuff works great because its user friendly and it does deliver results.
As for my opinion on individual products,
The Wash pad is my favorite pad Ive ever tried, the Detail spray works very well IMHO, the VRT is great for interiors (I don't like it on exterior due to durability), the BSG is hard to remove but does pretty well at hiding imperfections. The carpet cleaner works well on spot cleaning, but not for large areas. Their MF towels may not be the softest but Ive never had them induce any kind of marring.
The product I am the least impressed with is the Swirl Remover, it stains trim on an ungodly level and it is almost impossible to get off. The soap doesn't seem lubricious enough as I get much more wash induced marring than with NXT or Megs GC. Other than that the only product that needs improved upon is the Butter Wax in terms of durability.
Cliff notes - Adams works great for general consumers, but isn't tailored toward enthusiast's like Autopians. They have some good products and they have some crappy ones, just like every other manufacturer out there.
