I have the iPhone 6. Should I just get the iPhone 8? Are the 8 and the x basically the same phones besides the screen and face ID?

Most usually upgrade every 2 years, & in that case the 7 would have been that phone here. So yes the 8 would be even more worth it.

The X has a bigger display, OLED display, bigger battery, better camera system & of course Face ID as you mentioned.
