I’ve always used Windows and am super comfortable with it. I have set up a dual boot with fedora but don’t use it because I have never identified a need to use it. I see a lot of windows hate, so what does Linux have that I need? What can motivate me to migrate? What is a good Linux to have for a desktop + steam?
Debian Stable is a solid choice as it has the best support and is a hassle-free experience. Maybe with KDE Desktop. Its the most userfriendly windows-like desktop i know of.
Optional: You can also install the MX-Tools from MX Linux to get some comfortable GUI system tools.
Yes, that with flatpak you get the best linux experience.
