I went from 6Plus to iPhone X and I must say I love it. Wondered about the screen real estate but haven't missed it, X's screen is really big and the camera is awesome. The one downside, the price. I love my Apple goodies but 2K for a phone feels a bit rich. Unluckily I'll be switching from my X for a while!
Hope that helps and let us know what you decide.
