I bought it after extensive market research and I am satisfied. My biggest concerns before purchasing it were the response time, scaling for MacOs, and bleeding in the corners.
Ultimately, the response time doesn't bother me as a casual gamer (it goes down to 5ms even though the default is 8ms). Personally, I don't see any issues, but I have never had a gaming monitor to compare it to.
On Mac, I had to go with 1440p resolution because the native resolution had very small letters, but I don't think I noticed any difference in performance. You can also find analyses on YouTube about this, and it seems that performance is affected in very specific use cases to a small extent.
Although the bleeding in the corners exists, I don't see it in day-to-day use. It's definitely not a problem for me, but it is inevitable in these panels. However, in normal lighting, I never noticed anything. If you turn off all the lights and watch a very dark movie, then it might bother you.
Something that surprised me coming from a curved display is that with this particular flat 27-inch one, even after a month of use, I still haven't fully adjusted to it and the texts at the edges seem quite far from my line of sight. After 10 years of having the curved one, I finally appreciated it as a technology.
Other than that, the monitor is an excellent choice. Although you can find similar features at a lower price, I believe the reason why its price is €100-€150 higher is because of its USB hub. It has so many ports and at such a good speed (10Gbps) for most of them, that for a similar quality USB hub, you would need to spend around €300. I know this because I have extensively researched top USB hubs. With this monitor, I can finally connect everything and they all work flawlessly, something I couldn't achieve for so many years with mid-range hubs. I have connected 3 hard drives and around 10 more peripherals, all at the same time, and they all work without any issues! The headache of peripherals not working due to low bandwidth has finally ended! And all of this by simply connecting the monitor to my Mac with a "regular" USB-C cable, which also charges at the same time.
In conclusion, if you need a 4K, 27-inch monitor with a powerful USB hub like me, this specific monitor is a top choice. Otherwise, you can go for a cheaper 4K option.
