28" 4k has ~158 dpi, so it makes sense to use 150% scaling for it, considering that canonical dpi is 96. But it is important to consider disadvantages of 150% scaling in general. While text and vector graphics could be rendered properly, there are plenty of non-photo bitmap graphics, which has to be scaled. And scaling it by 2 keeps it sharp, while scaling it by 1.5 makes it blurry. Therefore it makes sense to buy either low-dpi monitors (with dpi ~100) or high-dpi monitors (with dpi ~200, and run it with scale 2), but 28" 4k is just in uncanny valley of dpi, that is too high for scale 1, too low for scale 2 and matching scale 1.5 is blurry.
