I hate the glare on the normal glossy screen. My concern with the nano screen are the micro etching. Are these on the outside or inside of the glass? If its on the outside, with all of the dust that lands on the screen, I can see crud getting into those micro etches and not coming clean easily (even with Apple's special cloth), and other time, really degrading the screen clarity.
I've had a relatively cheap LG 4K display for years now that has a matte surface. It doesn't reflect badly, it's a joy to use, and for some reason, it doesn't attract dust anywhere near the MacBook Pro display. Colors are sharp and vibrant. It cleans easily and doesn't smudge. The screen coating hasn't peeled off like on the MacBook. It doesn't have any micro etches either.
