I find it a lot easier to read, personally. Less eye strain. Most of the windows apps I use, at this point, finally support it (a few stragglers). The only downside I've found is that cabling can be complicated (not every HDMI cable is 4k enabled), and if you're a gamer, it's a lot easier to get a 144hz refresh rate on an older 1080p screen. (Which is also one of those things you probably don't realize is really nice until you actually use it)
