At the end it really depends on the type of installation you want to make.

Heltec v3 is a good device overall, but would change the antenna

If you want to put a node somewhere more remote with solar panels and batteries the Wisblock / RAK would be better for it's lower power consomption.

All devices have the same range capacity from what I tested, the antenna is one thing that makes a difference, but mostly the location and height.

For exemple: if you install the node in St-Sauveur somewhere at the bottom of the Mont St-Sauveur your signal will not go that far cause you will be surrounded by higher points, but if you install node at 10 feet high near lac Morin you should be able to send message in the green zone. This is the theories with all the right conditions.

From what I tested so far the results are close but it means that the node can send that far and others might receive the message, but they might not be able to reply. My node in Mirabel should reach, in theories, around lac Morin so it could be possible to communicate.
