These monitors are, with some qualifications pretty great. 144hz gaming is a dream, and I think it's going to be hard to ever go back. I'm permanently ruined. The colors are also pretty good, though not out of the box. The first thing I noticed is that the whites... weren't white. They were some kind of orangy off white. I was able to make some color adjustments so that the screen looked good, but be prepared to feel a little let down when you first turn it on. Just know that it can be fixed, and once it is, you're golden.
edit: For some reason, an entire paragraph explaining the photos has disappeared from this review. Weird. Here's the short version: One panel came with a tiny, tiny speck of dust under the glass. Another came with a dead pixel. According to Nixeus, the one with dust under the panel can be sent in for warranty repair, but the one with the dead pixel is not. The dead pixel one I expected. It is common to have a threshold for dead pixels. In practice, I don't really notice either.
So, are they worth it? I say yes. Sure, both of them had some kind of defect but on the other hand I paid $360 per monitor instead of $430-500 (the price of competing panels). Just know that the quality control seems, in my case, to have been a bit spotty.
I'm afraid I have to update this once more. I am having yet more problems. The on screen source select is popping up intermittently on one of the monitors during use. I have them mounted on arms and I think it has something to do with some wobble it might be experiencing. Remounting it and changing how tight the mounting screws were has helped, but it hasn't totally eliminated the problem. . I've tried vacuuming the buttons and blowing compressed air into their crevices, but that hasn't helped either. I have no idea why shaking the monitor very gently would register as a button press. If it gets much worse I will be sending both monitors back for warranty repair (it's the one with the dead pixel). The monitors are good, but I'm now fed up to the point that I want to be made whole. I'm not looking forward to the hassle of shipping two whole monitors but such is life. I'm knocking off another star for my trouble. Surely my time is not worthless, and maybe I would have been better off spending a tad more money.
