Simple physics of acoustics determine BTE as superior as well. Sound outlet (either by speaker or by tube, deep down into the ear canal, microphone(s) mounted behind the pinna of the ear. Allows more people to be 'open fit' for less occlusion effect, feedback resistance is greater due to the larger distance, etc.

Repair cost is lower because there's no custom nature to the BTE 'instrument' itself. In the ear models have the electronics mounted to a custom fit earpiece - requires units to be sent in for repairs, whilst BTE are simply just swapped out for a new electronics set.
