In terms of the specs, the Gigabyte monitor comes with a 34-in curved VA panel, with a 3440x1440 (21:9) resolution and 144Hz refresh rate. The monitor meets the DisplayHDR 400 certification, meaning it can accept an HDR signal and get reasonably bright (500 nits) to offer good contrast (~3000:1) between dark and light areas. Colour accuracy is also a strength, with coverage of 90% of the DCI P3 gamut and exceptional Delta-E values that makes this a great choice for colour-accurate work (if you have a colourimeter on hand to calibrate it - otherwise it’s merely good). So what about alternatives? Ultimately, there are monitors out there that can get brighter, or operate at a higher refresh rate at the same resolution, but these models tend to cost considerably more - for example, the Odyssey G9 is amazingly immersive in ultrawide games, but oft retails for four figures. This 3440x1440 144Hz spec really is the sweet spot for ultrawides right now, and $400 is the best price I’ve seen for a very long time. The only similar monitor I can find is the admittedly good AOC CU34G2X, which looks to use the same 34-in panel, but it’s $50 more expensive! So - if you’re mulling a monitor upgrade, consider the G34WQC. At $50 off its normal price, this is an awesome time to pick one up.
