I use bitmap fonts as much as possible and I turn AA off for all fonts below a certain size (18 px IIRC). I also force Firefox to exclusively use Arial because of the excellent hinting.
Things are so much more legible and crisp it's not even funny.
(Edit: Funny thing is, I remember font smoothing as much better in general maybe 10-15 years ago. Perhaps it was just the novelty that appealed to me then.)
I find the rendering on Linux (KDE Neon and openSUSE for me) to be vastly superior to Windows 10. It was already very good on my old 27" ~108ppi display, but it's even better now that I have a 4K display that's ~163ppi, which I run at 150% scale. Crisp shapes, no blurring at all.
It's all at default settings, subpixel rendering on and slight hinting.
Can you point me to some docs about how this can be done?

Make sure you don't have this in your fontconfig:
<match target="font">
<edit name="autohint" mode="assign">
<bool>true</bool>
</edit>
</match>
