Depends what you want, why not through in RWGPS as it shows your data better has segments (though not in order of done on the ride) I.M.O. better mapping export to a tcx course file or gpx navigation file for older garmins, the tcx course file will load as a breadcrumb on certainly the 500 (presume the 200 and others)
MMR didn't keep going back to it like RWGPS or strava, I don't need to use either really other than to see if I still manage p.b.'s on strava or rwgps, there are more segments on strava as others use it more than rwgps for segments, do to have the same segments on rwgps I have to create most of them and can't be bothered these days unless there is a big hole in the ride somewhere.
