macOS Catalina vs Mojave sub-pixel antialiasing

Hello there! As we know, Apple nuked sub-pixel antialiasing in macOS Mojave, making non-retina displays obsolete – fonts on the 1080p screens are looked jagged by default now. But one could still enable antialiasing partially using these commands:

defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

defaults -currentHost write -globalDomain AppleFontSmoothing -int 3

Then in some apps text looked awful and in some apps just ok. However, in macOS 10.15 Apple make some changes once again and so after updating from Mojave fuzzy fonts are back. Also on MacRumors forums somebody guesses that the solution is to undid the old commands that worked on Mojave:

defaults -currentHost delete -globalDomain AppleFontSmoothing

defaults write -g CGFontRenderingFontSmoothingDisabled -bool YES

"...and text clarity did improve compared to how it looked right after upgrading to Catalina"

That said, others argued that proper sub-pixel antialiasing is completely destructed in 10.15, like this:

(On the top is High Sierra, but it's similiar to Mojave with two first commands above)

Considering the problems I had with last restore to macOS Mojave, I need to ask the community (before my next attempt to update): does anybody use 1080p monitors/iMacs/MacBook Air with Catalina after updating from Mojave? If so, did these commands above help you to enable Mojave-like antialiasing? Or may be Mojave-like antialiasing is unattainable? Please leave your feedback about Mojave vs Catalina antialiasing
