First of all, Apple or any of their devices are never authorized to use my face, which is copyrighted in Hollywood.
I did use face ID for a short period in the early days of X but never get used to it (besides above reason). Touch ID worked every single time without fail (in my case). I guess it's partly because of the way I use a mobile phone. Almost 80% of the time, I use it as a wallet (ApplePay and many other store cards, and some digital ID's) in retail store front (Canada). I do carry a real wallet with various cards inside but I seldom, if ever, had to pull it out. I did not like touching dirty bills anyway. Then, pandemic happened and it is even more useful. Yes, anyone can argue face ID is just as much, or even more convenient for the wallet purpose. Perhaps. But It's Just_Me who prefer touch ID because I got used to it over the years and it seems more natural and secure to simply press the button to pay. I have nothing to criticize people who use face ID. Apple made a big deal on the security level of face vs. touch ID when promoting X. But there are many security holes or weak links in any device and be it 1million times or half a million times more secure is an artificial Apple sales talk and futile argument. Otherwise, I use my phone mostly for "checking & reading" emails, texts, and occasional (very rarely) phone calls. Except returning short and quikc responses to text mssgs, I normally author responses to email etc on desktop or laptop anyway (YMMV). As far as the functions of both ID methods are concerned, both are useful and I believe it is just a matter of accustomedness and preference. The way I use, a mobile phone is not a treasured toy to me, and utility is the only thing I am interested in. I happened to be biased toward touch ID, combined with the fondness of smaller device. Well the SE's are the only available (and excellent) choice for me now anyway.
