I actually find that it blows Google Maps out of the water for cycling (which is why/how I discovered it). I haven't really used it for driving much because my own car has a builtin nav, so can't really comment on that.
YMMV of course.
Left from Maps.me to OM because of drama and intrusive features, do I need to leave OM for CM?
edit: seems CM shouldnt have that annoying gift icon
edit 2: CoMaps doesn't display (colored) hiking trails, so completely useless compared to Organic Maps, also can't even display tram lines after tapping on tram stop in Prague
I personally also need hiking trails on my map, but I know people who don't and happily use CoMaps.
