Honestly, I am completely happy with this monitor. Majnu's settings sealed the deal - I feel that I am now very close to IPS-quality colours. I love using this monitor and whether it's work or play it is brilliant.
I know how familiar you are with fast IPS panels, so I'll try to compare this to the PG279Q which I also owned until I sent it back.
First, the good bits...there is none of that disgusting orange bleed. I had some BLB (silver) along the bottom of the monitor, but somehow it has completely vanished over time. So no glow and no bleed. That, for me, is a big deal as I found even moderate glow (i.e. visible in dark scenes) completely broke game immersion. Next, uniformity is perfect. Crisp and white everywhere - top to bottom, left to right. No yellow / brown staining to make you dread opening Word fullscreen! Then of course the price - it's now £300 cheaper than the PG279Q. That's plain absurd - with the money I've saved I'm going to buy a new chair and Corsair SP2500 sound system and still have change. I would say it's also much better built than the PG279Q. The monitor wobbles on its stand when you press the OSD buttons, but honestly that's the only quality-related niggle I can think of. You should also benefit from Dell's warranty service, which for this monitor includes next day replacement delivered to you. A far cry from Asus BS. On that note, you are much less likely to get a faulty one. Finally, I actually prefer the design (subjective, of course!) as it has slimmer bezels (with no foam inserted lol) and looks more professional.
The bad bits...well for me the biggest problem is the vertical colour shift. You won't notice it in games really, and even desktop use doesn't really reveal it. However, if you work with full-screen images you will see the shift. I did a report for a company here that use deep orange as their signature colour. Some of the pages I produced were that colour top-to-bottom...but on this monitor it appeared to be a gradient shift from dark to light, with only the middle of the screen displaying the 'right' colour. I don't notice horizontal shift from my use.
Pixel inversion is also something of an issue, but it rarely stands out. I saw it once playing the Witcher and once playing Grav. Not seen it again since, so I can't say it bothers me at all. There is also a degree of overshoot, but IMHO this comes with the territory of a 144Hz monitor and is less noticeable than it was on my old 144Hz panel. So again not something I mind. The monitor lacks a dedicated gamma control (although so does the PG IIRC?) but this is mitigated by the excellent ICC profiles available now. Also I miss the PG's joystick - that was awesome.
Overall I feel there is really no contest. Even if they were priced the same I'd pick the Dell due to the failings of the fast IPS panels. I just feel that the fast IPS screens need to mature a bit. I'd rather have the very best of an older, proven technology than the faulty first attempts at something new. And that's how I consider the Dell - the very best gaming TN you can buy if you are after the 1440p / 144Hz sweet spot. The money you save can be stashed away - it'll probably get you halfway towards a new OLED screen sometime next year!
I'd give the Asus a 6 / 10 at its current price and a 8 / 10 if it was the same price as the Dell, which I'd give 9 / 10. I'd rate the Asus a perfect 10 if it was fault free and ~£600, and 9 / 10 if it was fault-free and £700+.
In fact, if I thought my cards were capable of it I'd seriously consider getting two more Dells (£430 atm) for a surround set-up - that's how much I like them!
