I think meshtastic would be a lot more performant in mesh scenarios due to the added range of LoRa. But of course it's special hardware and thus suspicious during an insurrection. And probably just not available. I doubt this will actually work though except in the densest city.
Meshtastic also struggles with high density and high traffic networks. Some modifications can be made to work better, but with the default settings it really grinds to a halt, and modifying the settings to be better suited requires some expertise and foresight. It works amazingly in off grid, relatively sparse networks, but it's got some major limitations.
