There are free maps with contour details, so it's not really a problem. Topo is not aware of most non-arterial routes and will try to route you via main roads as it isn't aware of that quieter option nearby. There is no need to set up lots of 'avoids' with City Navigator. These days I plan my routes on bikehike since they started supporting the gpxx (note - gpxx NOT gpx) format. This means you can create a routable ride on bikehike and export it to your Edge and have a full routable (turn left on acacia avenue, turn right on the high street etc etc) route. Plus you can see the elevation profile before you download.
Also, if you find yourself in unfamiliar surroundings and want to re-route somewhere, all that pre-planned work you did with Topo on your PC is for nothing. There is no way to plan a route on the Edge itself that avoids hills etc, so I'd much rather have the proper road mapping product on my Edge.
You seem happy with your choice though, so who cares
