Touch ID is significantly better than Face ID. Way less false positives. Way less false failures that force you to enter your passcode. You can use it in the dark. You can use it in your pocket. I ditched my iPad Pro for an iPad Air specifically because it has Touch ID rather than Face ID>
Want to exit the app? Tap the home button. Select an app? Double tap?
What's wrong with swiping up? Where you swipe from varies depending on the orientation of the app. That may not always be obvious. With a photo for example. Is it oriented a way because of the phone's rotation when it was taken or because of the phone's rotation now? The gesture to get to app selection is super awkward (ie swipe up-right-up). It's so awkward.
Why can't apple put Touch ID on the back? Or on the sides? Why can't they have a physical home button (even one of the haptic feedback buttons) on the back?
Losing the home button is such a UX fail.
