FaceID works better when your hands are dirty or unavailable (e.g. you're wearing gloves), TouchID works better when your face is covered or your look changed slightly[0].

FaceID has been a strict downgrade for me, there are very few situations where FaceID works and TouchID wouldn't have, the reverse is a daily occurrence. And things would be even worse if I couldn't work from home, as TouchID works just fine with a mask.

[0] in bed without my glasses FaceID works 0% of the time, even resetting the entire thing and re-registering my face with and without glasses, it works all of 2 days before it stops recognising me without glasses.
