I think (I may be wrong) that they provide the RIC (RITE) hearing aid with too long a cable to the receiver, which can alter directivity and beamforming upward, which can be detrimental to sound quality, especially if you are tall. See links below; however, I see no contraindications for BTE—it provides a nice, repeatable, stable position.
Personally, I had BTE long time ago - Phonak Bolero, Oticon Inteo, etc.
You didn’t mentioned which acoustic coupling you had with Philips and with Jabra - closed domes? Vented domes? Earmold?
