One major downside of Touch ID that is niche but affects me personally is that if your fingerprints get damaged (e.g. by rock climbing, which I do regularly) then Touch ID will stop working for ~1 day while your fingers recover. For this reason I'm planning on getting a device with Face ID or a similar feature next time I buy a phone. The downsides of Face ID you mention are valid, though.

Add your two thumbs and two index fingers so that you can use any one of them depending on convenience or rare edge cases like rock climbing damage to one of them.
I have a scar across my left thumb from working in kitchens in my 20s and touchID seems really unreliable on that thumb.
