I currently have XPS 15 with 4k screen and I can easily see pixels, so 14 should be a little better. There is also the feeling that it is 2021 and should I still be seeing pixels? I think crisp high resolution view is much better for the eyes and feels more natural. I am also almost always within reach of a mains socket, so I don't particularly care about battery life, just that I can move the machine from one place to another easily.
