I'm the same way. I was an iPhone 7 hold out for a long time because I didn't see the value in Face ID or any of the other stuff and now I really regret holding out as long as I did. Face ID is so seamless and it's just so much smoother to do everything. Going back to my work phone is more than a bit awkward trying to remember how many times to tap or double press to do whatever. On the iPhone XS I have the gestures really make a lot of sense to me.
