I agree. You really cannot be brand loyal in this business. I like the CG products I use but I do use other brands. Some of CG products really do work great for the money.
I use CG, Optimum, Menzerna, P21s, Garry Dean's, Blackfire. The list goes on. The trick is to get the most out of each product you can. I hate reaching for a different bottle for every little thing and that is sometimes what you get with CG. They have a lot of overlap in their product lines.
So do your research and decide from there. In terms of pricing with the exception of a few things I think pricing is pretty fair if not better then some other brands.
I'm a huge fan of the V line polishes, shampoos, VRP and no one can talk me out of Pete's 53' it's a great wax for the money.
