The thing I've come to like about FaceID on my 13 mini is that I can require it for certain apps to open that don't require it - e.g. messaging as opposed to banking which generally require some kind of auth by default - which is much better security in case someone snatches it out of my hand while it's unlocked. It's pretty seamless because I'm generally looking at the device anyway, and it's much less faff than it would be with TouchID.
