I have CN, and I also have RA with my insurance company. CN was free for a year with my new purchase.
I hope I never have to use it, but as much as I travel (or want to travel), I probably will.
Im thinking about going AAA when CN expires, or maybe even keep CN and buy AAA. Gotta do some more research.
I think there's good stories and bad with probably all of them. If they couldn't find a company that takes CN (or knows who they are), that's kinda disturbing.
I suspect response time is a function of the individual tow company, not the roadside assistance company.
