The physical size of the 8 and this new SE is pretty much the same as the X/11 Pro (it's only smaller 5~6mm in height, 4mm in width, 0.4~8 mm in depth). If you were holding up on your 8 because of that, I'd say you can fork the 1000+ bucks for the X or 11 Pro, it will be an upgrade in every dimension except Touch ID disappearing.
