look at the ppi of the 6,7,8 a smaller screen phone also. a 6.1" screen with that level of ppi is just not as high of quality screen as the smaller iPhones. similar yes but no where close to the + phones or the oled phones.So you paid $1k for the X. Meanwhile, I can get the XR which has more advance SoC than your X, still retina screen at more than 300ppi, and for $250 less.
If you only look at ppi, plenty of Android phones better than your X
Geekbench so far is out on the xr and it isnt any better than an X from a year ago. The x is a better phone then the xr sorry it just is
