Reticulum has built in support for sending or receiving data on multiple layers like internet bluetooth wife etc. Mestastic doesn’t. Also meshtastic can be less resource efficient cuz it sends a lot of probing messages.

Edit: lol, wifi not wife, but who know maybe wife can also forward messages from reticulum

Theres no place for nuance here, get outta here! /s
