I recently (a couple of weeks ago) got the 6K version of this screen, the Asus PA32QCV. It has the same pixel density as my MacBook Pro, so the UI looks great. To be honest, it's enough screen real estate that I now operate with my laptop in clam shell mode.

My only complaint is that the KVM leaves a bit to be desired. One input can be Thunderbolt, but the other has to be HDMI/DisplayPort. That means I need to use a USB-C cable for real KVM when switching between my two laptops. I'd like two cables, but four cables isn't the end of the world.
