Five, maybe even six or seven years ago I was regularly using Strava, RWGPS, and MapMyRide all at the same time. With the free accounts, one always had a function or two the others didn't allow for free. Don't know how that holds today.

At the time, MapMyRide was actually my favorite. However in the end, RWGPS won out to get my subscription money and I don't regret it at all. The few times I've had to email RWGPS's support a question, someone got back to me the same day. Even within the hour I think.
