Absolutely loving it - really easy to set up, initial settings look great (and better still after using Nvidia settings), working perfectly for both gaming and productivity. The OSD is excellent and easy to use with the remote. A tip - I had to install the Asus drivers to get my PC to recognise that the monitor has HDR capability.
Negatives? Well, there are some very minor ones, none remotely deal breakers though. The sound quality clearly assumes you have some other speakers, as it's not great. But I do have other speakers, so I'm happy not to have paid extra for speakers I had no intention of using.
I'm having to find a workaround to get it on my existing Vesa arm-mount, as the screws that fit the monitor are too wide for my mount (I have some thread inserts on the way). And finally, while the continental kettle plug is right angled, the UK one is straight, which means the lead when plugged in is clearly visible to the left of the screen, so I've ordered a 'left angled' kettle plug.
None of which detracts from my enjoyment of a superb monitor that I don't expect to be replacing for many years. If you are thinking of buying, do.
