Text honestly looks like shit an any non 4k external monitor for macOS it's kind of crazy how bad it is compared to windows.
At work I have a mac mini and a Windows box, and I use three crapola Asus monitors between them, and my impression has been that macOS does a better job rendering text on said crapola monitors (the Windows box does a better job at compiling C++ in a timely fashion, though, so I mostly work on that one).
But yes, I didn't know that they ripped out subpixel rendering in late 2018 by default.
In general with a HiDPI screen I don't find any need for it. But on a low-res display like the typical 24" 1080P models it certainly helps.
