I feel exactly the same, the font rendering in Linux drives me absolutely insane. The amount of hours I've spent over the past 15 years tweaking fontconfig, having to compile special patched packages etc etc doesn't bare thinking about.
I don't even have to edit anything on Windows now, and when I did a few years ago it was only on a clean install going through I think what was called cleartype config, you had a panel of 6 images/samples to choose from and after going through it all everything looked pretty damn perfect.
I'm currently using a Mac for private stuff, used to use Linux for work stuff, currently forced to use Windows. My font rendereing ranking is MacOS > Linux > Windows.
I rate it macOS > Windows > Linux. iOS is pretty good too, mobile Windows wasn't. But I'm only experiencing Linux graphically on a rather old monitor or through a terminal emulator, and macOS and Windows on a nice monitor, so that probably skews my perception. I wonder how many people observe the three OS'es through the same (or very similar) monitors.
