Oscillating vs. impact vs. gear-drive: which sprinkler type should I buy?

Oscillating sprinklers are best for rectangular lawns and gentle, even watering. Impact (pulsating) sprinklers cover larger circular areas and handle low water pressure and debris better, making them a favorite in r/Irrigation threads. Gear-drive rotors are quieter than impacts and good for medium yards but can struggle at low PSI according to r/lawncare discussions.
