You are missing the point I made, which I think started this whole back and forth. Apple should not include the ears in their diagonal measurement of screen size if you/they want to say its "extra" space. Otherwise its "removed", not "added". Its pretty simple.
But it doesn't matter. The relative difference in size between them is negligible, looking at the scaled picture of the two side by side. If you like the notch and in your mind it gives you extra space, then that's great ... the X is a great device. If the notch bugs you and you don't like it, then get an 8, 8+, or S8. The good news is that they are all awesome smartphones. Choice is a wonderful thing. It would be pretty boring if they all looked exactly the same.
