I used them for a while. No problems that I remember (although not used for massive rides) but the same issue as the OSM maps in that search is a bit flaky with no postcode search.
The road priorities are set up differently so routing will give you different routes, somewhere in the FAQ it tells you what the different settings do (seem to remember you should set it to car for road cycling) but it would still give overly long routes.
Anyone used https://www.velomap.org/ ?
I want to try something different to see if it's any less flakey than Garmin's own maps on the Edge 1000 SD card.
