map
Camera + map(not satellite) gives me the best spacial awareness.
I fly mostly in build up areas. The map gives me so much detail.
I can immediately see what is directly below and around the drone.
The map shows me the streets, water, park etc., and when zoomed in it even shows the buildings.
It also shows a direct line to the home point, to easily know the relative position.
It's also easier to determine if there is a magnetic issue. I just look f the red arrow is lined up with the street the same way the drone is. No need to know where north is.
The radar will just lose you the ability to see what your drone is flying over.
I don't really know what the radar does that the map + telemetry does not already give you.
