KDE Plasma is just the desktop environment. It’s not an OS. SteamOS is a full OS, built off of Arch Linux. It has both a Gaming mode, which looks a lot like Steam Big Picture does these days, and a desktop mode that uses Plasma as the graphical shell/interface. It doesn’t matter OS-wise which one you “boot” into, as both are SteamOS.






I’ve heard of Zorin before. It’s been around for a while, but last I heard anything was years ago. There’s not been much hype or anything since.
