coming from an iphone 8+ plus, I find the Xr a tad too narrow, with similar SETTINGS the text just seems to be squished from left to right. It's taller, great but I like that little tiny bit of extra fuller page reading view. It also is thicker, tiny amount mind you but I can feel it. It also just overall FEELs heavier even though the difference is very minimal.
If only they could have made the Xr same overall screen width, more height (which it has) and maintained the thickness of the 8+ or thinner even it would be pretty perfect. Not really sure why they didn't/couldn't other than protect Xs share. They SAY it's a bit thicker because of the screen, but the 8+ has a similar screen technology and it's overall thinner.
In the end, I'll stick with the 8+ another year. I DO prefer/enjoy the full screen UI experience though and wonder why couldn't we get that in a software update as an option?
