So about a month and a half in, I'd have to say this is probably my favorite version of the iPhone. Love the screen, a large OLED is most welcome, and I adjusted to the lack of home button and notch far more easily than I would have anticipated. A notch less screen future would of course be ideal whenever that happens, but the thing is much less of an issue than I was worrying it would be. And the gestures work great, instant and responsive and natural. Overall the phone looks great with a great display, and of course performance wise and photo/video is top notch.
On the negative side FaceID is solid but for me still not quite as seamless as TouchID was. In general usage it's great, but certain moments were I'm not looking directly at it enough when I want to check my phone happen a little too frequently. A couple of my main apps seem to lose the option to use FaceID randomly and that's annoying. And some of the OS interactions feel less intuitive with FaceID, like say a new app download that requires a double click of the side button vs just reaching to tap the TouchID home button.
In a side note, finally saw an XR today and it's a great phone. Screen still looked good and if it wasn't for the fact that I wanted the larger OLED it would have been an easy buy.
