In case you’re having a tough time deciding between an 8 Plus (MSRP $549) and an XR (MSRP $599), note: (8 Plus is $319 here and the XR is $399)
Even though the 8 Plus is a physically bigger phone, the XR (and identical screen/case sized 11) actually has a bigger screen. 5.5 inch on the 8 Plus vs. 6.1 inch on the XR & 11. Even the 11 Pro screen (5.8") is smaller than the XR & 11.
The only way to get a bigger iPhone screen than the XR & 11, is to go to the XS Max or 11 Pro Max which both have 6.5 inch screens. The case sizes of the XS Max, 11 Pro Max, and 8 Plus are about the same.
The iPhone 8 is the last iPhone with a home button. Giving up the home button (a physical button is a potential failure point) is no big deal - especially in exchange for a larger screen in a smaller case size.
Face ID on XR/11 works amazing in all lighting. I have well-scared finger tips from decades of woodworking/welding/etc… and Touch ID (the home button) never worked that great for me.
8 Plus=5.5"… XR & 11=6.1"… XS Max & 11 Pro=6.5"
8 Plus=6.24x3.07"… XR & 11=5.24x2.98"… XS Max * 11 Pro=6.22x3.05"
