I would think that it would be very difficult to have a "favorite brand." In the six months that I have been an "Autopian," I have watched, and learned.
I have products that I had used, but do so no longer. I have products that I still use, and rely on. I also have products that I am "testing," and may or may not keep them.
Also, there are products that I am thinking about using in the future.
That is the fun of all of this. I understand that getting the "product lineup" for one's car is a trip unto itself, and yet, it may change.
But, I am beginning to believe that the journey is more fun than the destination.
Having said that, I have no problem with fellow car nuts having favorite brands.
I just have to think that most every serious detailer has an "arsenal" of products that are not brand-exclusive.
That's the fun part of all of this, and we all know that the "arsenal" will change over time, as long as the credit card allows.
