Meshtastic has a TTL of up to 7 and (from what I've been able to understand) uses flood routing largely. In Northern Colorado (where I'm at) we don't have a particularly dense mesh, but are turning down from 7 because of congestion.
Meshcore seems to (I'm still learning on this) use a TTL of 64 and flood to find a route to a destination, then uses source routing for future packets, reverting to flooding again if that path fails (say a mobile repeater moves out of range).
