It’ll be delivered in a couple of weeks. I’ll use both for a while, and reply back to this thread for posterity.
As to the screen, I was immediately pleased. The difference, I think, is that Apple stores have perfect lighting. There are no reflections, so the screens look as good as they possibly can. If you have a photography studio or something, you probably do still want the glossy screen, as it has deeper colors in perfect conditions. But in my house, the opposite was true: since there were nearly always some form of reflections, minimal or otherwise, the nano-texture screen actually appeared to have _more_ contrast, since my eyes didn’t have to fight to concentrate at a certain depth in the screen.
I put some 4K HDR videos on both, and honestly couldn’t tell the difference. I could tell a slight difference in the terminal (Alacritty, Solarized Dark) in that the base blue color appears slightly different, but it doesn’t bother me.
I’ll post again if I notice anything else, but my immediate reaction is that the nano-texture screen is better for most people, and to not rely solely on in-store experiences to determine preference.
