I did because I wanted the better camera. It’s my only camera, so I always opt for the upgrade. I was really happy to have portrait mode back completely (instead of limited as on the XR), and my photos have been exceptionally clear and detailed.
The improved LTE was also a draw for me, and I do seem to have better reception at home (which was my issue - we are in the boonies).
I also bumped from 64 to 128 gb (only $50 jump, which is not bad at all), and even though I wasn’t using my entire 64 gb, I really like knowing I don’t have to watch myself with videos of the grandkids. ;-p
