Please dont think that everyone in world prefers to some models just because its inexpensive. I myself had XS max for 1 year and then went back to 8 plus for two reasons
i) The screen real estate on 8 plus is much better than that off XS max even though the screen size is more in XS max. The aspect ratio on 8 plus is 16:9 which is perfect for browsing , XS max seems narrower
ii) That notch on xs max is something that i cant accept (though i used XS max for 1 year, got a nice resale value so bought a 8 plus . since then using it)
i would be ready to pay to even 1500$ if apple removes the notch
