People who studied the code speak really fondly about reticulum, however, it's not as popular for building the lora based mesh networks, because the full stack does not run on the simple microcontroller. You need what is basically a standard PC connected to it. Given that mesh repeaters are usually designed to run off-grid on solar and battery, wasting additional power for a raspberry pi or similar computer would make the project unfeasible.
All while Meshtastic or Meshcore are perfectly happy with the esp32 or nrf microcontrollers. And the nrf ones can run without a direct sunshine for days with the reasonably large battery.
They're working on fixing that ;) https://github.com/attermann/microReticulum
