What Class of Monitors is Comparable to iMac Retinas

Has anyone tried the Asus ProArt Displays?

While not retnia, 4k UHD factory color calibratedwith display port over USB c is checking lots of boxes for my next monitor. I watched a couple YouTube reviews, apparently they’ve been for a little while but I haven’t heard of them mentioned on any Relay shows. There’s a few variations and sizes.
