Helicopters can shoot from 500ft+ and cover vast areas which is suitable for large sites or to show a property in relation to a city centre or infrastructure. Helicopters can fly for several hours and for hundreds of miles at a time and cover many sites far apart.
Drones are more affordable, maneuverable and suitable for low-altitude (below 400ft) shots. They can be used at short notice and fly low over built up areas.
