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?
IMO when you migrate to Linux, you can learn many things that you never think about before and it give you the easiest solution for daily life. From piracy, privacy, ideology, and deep tinkering other things that you can’t do on Windows (Coreboot / Libreboot, or HAM Radio hack for example).
Pop! OS is the best choice you have. But if you want to create home desktop for your family using it, I recommended Q4OS with Pure Profile installation, just install Firefox + Ublock Origin and you can go perfectly good…
