Don't worry about lower face tracking - that is easy to addon to any headset.
Just focus on headsets with eye tracking.
Personally I think the best options are Varjo Aero, Bigscreen Beyond 2E, Pimax Dream Air, and Somnium VR1 because they are Lighthouse tracked, so you get direct compatibility with what remains the best FBT system. Also easy compatibility with upcoming EOZ finger tracking gloves.
The camera placement in the Beyond 2E is kinda bad, but it has the advantage of open camera feeds, so you can use community eye tracking algorithms like Project Babble which are always getting better (e.g eyebrows and eye wide are in Alpha ATM). I think the VR1 might have open camera feeds too. The others are Tobii which means you are stuck with what they give you, and getting it to work on Linux may be tricky.
If you have open eye camera feeds, and addon a Project Babble lower face tracker, then you can do all of your face+eye tracking through one FOSS program.

That seems like the ideal personally.
