What OS do you use on your pc and why?

I main macOS currently. And use KDE Plasma on my Steam Deck and then I have another PC that was a Windows PC that I flashed Pop!_OS on. And I really like it. It definitely feels like a Linux and macOS had a baby. But I am curious about trying a different distro.

I have a decommissioned work PC with Windows for things like MS Access or whatever strange reason I need a Windows-only application.
