It looks like the main feature, but not the only one, of ACA is maps. While the information about stores, campgrounds and free lodging sites seems worthwhile, I doubt anyone would be interested in them if not for the maps, and that is my main problem with ACA. For the places that I am intimately familiar with, the routes chosen are generally quite poor. They seem to value access to commercial resources higher than avoiding dangerous road/traffic conditions. I often get from A to B by more scenic and mountainous routes than what recommended by ACA and deal with orders of magnitude less traffic. That said, access to commercial amenities is probably more important to most Americans than it is to me, so they are likely serving their audience okay.
