It doesn't matter what route planner you use (they all produce files that work equally well).
Ridewithgps is a bit easier to use and has more features. (Unlike ridewithgps, Connect isn't Garmin's core product.) Ridewithgps is more "open" (I often load the gpx files into other apps).
Using the same map to plan that is on the device can make things work a little better but, usually, that doesn't matter.
The planners use Google maps (usually) but allow the use of Openstreetmap (OSM) maps.
Generally, the maps used on the Garmins are Garmin's CN maps or OSM maps. The newer Garmins come with OSM maps.
Garmin Connect doesn't support "course points", which means that, if you have a 5xx, you might do better using another planner.
