The only thing I don’t like about Face ID is the Apple Pay process and double tapping the side button, especially when at a merchant like a fast food restaurant or what not and trying to do it in a hurry. Where Touch ID just seemed more fluid with Apple Pay, otherwise Face ID is great and I’ve noticed an improvement in speed since updating to iOS 13.
I do agree with you on this but now that I have an Apple Watch I always use that for Apple Pay because it's so much more convenient than getting out my phone.
