I've been very pleased with the ACA maps I've used. I think one of the biggest advantages is that they take you off the highways and onto peaceful, bucolic roads when they can. They also have lots of helpful information. No, they're not perfect, but they're so helpful that I'd consider following one of their routes so I could use the map. Having said that, I don't want to discount the fun of creating your own route, and making changes along the way. Of course, you can sort of do that with ACA maps by either choosing a different road for part of the ride, or deciding on stops as you go - not following a pre-planned itinerary.

I have not found that they lead you onto dangerous roads. My experience has been the opposite - the routes avoid them.

I used Google maps to plan a tour last spring. I ended up on a road which first turned to dirt and then vanished. All I can guess is that the road is on the drawing board and they've started constructing it but haven't finished. I had to backtrack and scramble to get back on track. I couldn't get to the campground I had planned on and had to stay in a motel. Not the worst thing, but I don't think it would have happened if I'd been following an ACA map, or a route that had been ridden and tested by someone else.
