The above also depends on the aircraft type. On the A320 auto-brake is designed to achieve a calculated deceleration rate.If you land with MED set and don’t select any reverse thrust the brakes are applied hard which sends everyone forward in their seats and the brake temperatures soaring. Selecting full reverse thrust as well greatly reduces brake demand and gives a much smoother arrival.
Obviously auto brake MED is normally used on shorter runways in conjunction with full reverse anyway.
