1440p (and by extension 5k) have advantages from a productivity point of view too. In my experience, no OS really consistently supports fractional scaling, so if you want a good time you want to run at 1x or 2x. In terms of how much "stuff" you can fit onto a screen at a comfortable size on modern monitor sizes, that means you'll end up using 1x for 1080p/1440p and 2x for 4k/5k.

1440p@1x or 5k@2k let you fit more than 1080p@1x or 4k@2x while feeling plenty large enough with modern application design on a typical (24/27 inch) sized display.
