degen I'm trying out Manjaro KDE (Kernel 5.10) on this laptop now after I saw @ravipra praise of it. I compared it to KDE Neon. Manjaro KDE is clearly better for the eyes than KDE Neon. Less tension in the eye muscles and temples. The text antialiasing seems a bit aggressive though on Manjaro KDE, but if I turn it off it's unreadable.
Next I will try and compare Manjaro KDE to Fedora. It would be great if it was better since KDE feels at home coming from Windows. I just can't get a handle on Gnome. Fedora 34 will transition their KDE environment to use Wayland as well so maybe I will wait for that to make my comparison instead of Gnome.
My first impression upon switching from Fedora to Manjaro KDE was that my eyes felt way less burning and irritation, but that text was harder to focus on. Need more testing.
Post 1507 Windows 10 is just not working for me so I need something that will work on newer hardware which 1507 is struggling to support (currently resorting to hacked drivers on a Comet Lake laptop..). So far my impression is that Manjaro KDE falls somewhere between Windows 1507 (good) and Modern Windows (bad). I'm excited since any improvement over Modern Windows is welcome.
Having fun with it as well.
