The only downside of this monitor is its size and resolution. At 27", 1080P pixels may look too big. Wait a min... That's IMO perfect pixel density. I have already 2 other 27" LG monitor at 1080P and from 2 feet away they look absolutely perfect.
As an artist & gamer I can still distinguish the pixels, but also, they are not big enough to affect viewing quality in a bad way. I prefer to be able to tell pixel by pixel because reasons.
Other than that,
144hz, Freesync, IPS panel that supports HDR10 at 99%SRGB.
Say no more.
Shut up and take my money.
