I have the same opinion as the author here. When I buy a 4k monitor, it's generally for the higher PPI. There's just less eye strain for me reading less pixelated fonts. Personal sweet spot me in terms of pleasant readability is: 4k 24" @ 200% scale (so same screen estate as 1080p) or 5k 27" @ 200% scale (same screen estate as 1440p).
