Until GPUs are man enough to run games at 3440x1440 at, or close to 200 Hz LG 34GL950F is the monitor to pick. HDR is still in it's infancy, and more pain than gain. It is good that this release is happening now, because when next generation of GPUs that could run games that high comes, and HDR is more polished monitors will be less expensive.
I would really like ASUS to drop that idiotic stand and offer something normal and discrete. I mean you pay 2700 BT (Bear Tokens) for a monitor, and you need to add another 200 BT for normal stand. It is stupid.
Why in the 7 circles of Hell do they need DAC on a monitor? I would understand it if they had proper high-end headset in their lineup so you can pair it with, fair enough. But they don't. People who rock studio grade headsets already have much better DACs than ASUS is offering.
Drop the idiotic stand, drop the useless DAC, and sell your product for 500 BT less. You will sell way more units, and you will earn more money.
