The difference is that missiles used jet propulsion and don’t use wings to generate lift. Drones typically used propellers and wings to fly. Now we also have drones with jet propulsion so the main difference is that drones use wings, missiles do not.
I don’t know about hover, there are drones that are basically small planes. My definition would probably include landing and being reused.
Most of those drones definitely cannot land. Even some of the reusable drones are bad at landing and are basically caught in a net instead.
