I’m honestly on the fence about whether it’s sharp enough for high-precision visual work, especially if you’re doing this professionally
It’s essentially the same situation as what Bryan Adams6 mentioned earlier; the only difference is we're looking at a 21:9 aspect ratio instead of 16:9. Since those extra pixels are only added to the width, it’s effectively the exact same thing—just different proportions

For those specific screen sizes, you'll want to go with 1440p resolution (which is 2560x1440 for a 27" 16:9 monitor, or 3440x1440 for a 34" 21:9 monitor)
Also, if you need to stick to just one retailer, I'd suggest Best Buy, particularly if you're in a rush. It's not that they can't get orders out the door, but they can be a massive headache if anything goes sideways—think returns, shipping errors, or getting your money back
