Try touring in Western Europe. There are minor roads and alternative, often counter-intuitive, routes everywhere.
I haven't toured with a dedicated GPS. I have used google maps, but wouldn't rely on them for the reasons cited above, especially the fact that network coverage is not ubiquitous. And call me old-fashioned, but I like paper maps, there's something aesthetically pleasing as well as practical about them.
