I've had it for a few months now and I really like it, but I may be blissfully ignorant, because I've moved from a 23" 60Hz TN Dell monitor that I've had for years... calibration may not be perfect, and the LG might be better... but I may never know! However, with the £600 difference I could also buy a 1080Ti... that quickly puts things into perspective. Right now though, my 1070 is doing a good job.
Build is solid. There is a bit of glow from both bottom corners, but I think some glow is to be expected, but I only see it when testing with a black screen, never with content on screen. Monitor movement up/down, tilt, etc is very good, though a bit stiff (but means it stays put after adjusting). The stand looks big, but it actually fits on my desk quite nicely, so better than expected.
