I have the Asus PG278QR which I bought 2-3 months ago and still notice the coating. It's my only complaint but I still advise you to go with the Dell.
This was the only monitor that came more or less perfect without needing to be replaced that I bought this year and I have had many.
As said I have nothing to compare it to, but the Dell has a massively premium quality feel and look to it. I don't think 165hz would bother me, mostly because my rig plays most stuff around 100fps on max settings. Even if I was pushing 144 frames, I don't feel like I'm missing out on the even higher framerates.
The couple of things going against the Dell, it's been out a few years now, maybe a refresh is soon due? But if you can get it at a good price (~£450-500) IMO it has a look future still and will blow you away![]()
Final question - what is the speed setting for on the Dell? I've read about text ghosting when in Fast mode? Does this mean i'll get ghosting if i run at at the advertised response time? Doesn't that sort of defeat the object? Or is the speed setting something else? See here on the Dell website:
