I can clearly sense that you have not even touched on the X. Dismissing the FaceID is the biggest mistake. Even after two hours of use I didn’t care about touchid if anymore.
TouchID is also cumbersome, it makes you do extra work with your fingers. Also FaceID shows it’s strength with apps. With touchid you would launch an app, move your finger to the Touchid ( after the phone asks you to) and get it unlocked, with faceid you just launch the app, nothing extra is really needed as the phone is pretty much already on your hands facing your face.
Also don’t compare the lumias “scanner” to FaceID as it’s so far ahead. It’s a completely different world.
