#meshtastic or #meshcore - how to find out what the others around you are using?
The lazy way: Compare https://map.meshcore.dev/ (meshcore) with https://meshmap.net/ (meshtastic).
And the obvious brute force idea would probably also work: Get a device, flash one of the two, try it out for a week, flash the other, try that out for a week.
(Have not flashed my own shiny new device yet for either. Intend to start with meshcore.)
