Design
The iPhone X is the Design champ here, with that edge-to-edge screen and lack of a home-button. The iPhone 8 and 8 Plus are much more familiar. All the Phones are IP67 rated, have glass backs for wireless charging and no headphone jack.
Spec
The new 10nm A11 chip powers both phones, though RAM has yet to be determind. The iPhone X gets the new OLED display, while the 8 and 8 Plus have to stick with IPS LCD
