HFP mode is not worth using for anything unless you are roleplaying a person from the 90s taking a phone call in the car.

The sound quality is truly awful in HFP mode, I can hardly understand what people are saying when in that mode and you sound horrible to everyone on the other side as well.

HFP supports multiple codecs, and if your headset and source support the more modern ones (e.g. mSBC), this is no longer true.

Important to note that afaik no Linux distro supports anything other than potato quality HFP at the moment - at least that's been my experience.
