I'm actually also very sensitive to audio quality. Oddly, I also landed on zoom has above the rest in terms of quality. Everyone on my team uses headsets, this avoids need for echo cancellation and the weird muting effectings that generates - so I HIGHLY recommend this - two people can talk at once comfortably so you pick up the little cues of interjections etc. Facetime audio only is good in quality in my experience, but not so great in latency (may be for reasons outside apple's control obviously).
