Own both the ASUS VG27AQ and LG 27GL850-B for both gaming and work - Haven't had issues with the LG monitor, been working like a charm. The monitor colour reproduction is pretty good - does need a little adjusting if you are into graphical work. The USB hub works fine as well, no drop outs. But nothing really very problematic about it.
But... two little things to mention - if you're planning to use a monitor arm, if may not be compatible - I'm not referring to the vesa size, but the interesting option to recess the mount where some arms can't actually slot in nicely.
Secondly, which is more of a cosmetic thing, which I find on monitors without a plastic border (on the screen plane) is manufacturers don't apply the film perfectly. My LG monitor has a 0.1mm'ish dot on the top right of the monitor (on the black border), it isn't intrusive but it's noticeable when you find it - similar to a tiny air bubble under a screen protector.
Terms of IPS glow - there is, but it isn't crazy bad.
