Meshtastic gives you three hops by default (and strongly advises against going beyond that, even if the maximum is seven). The furthest node I see right now is about 200 km away.

MeshCore gives you 64 hops. They can afford that because MeshCore devices send way less telemetry by default; Meshtastic assumes that you want to broadcast e.g. your GPS position regularly. The furthest node I see right now is about 50 km away.

By the way, while LoRaWAN is a thing, neither Meshtastic not MeshCore are really designed for data traffic. Owing to the low (and shared) bandwidth, they're more like IRC over radio.
