I started with FreeBSD, Fedora, and Debian, and was comfortable on all three. I’ve run OpenSolaris and NetBSD in the past too. I experimented with Nix OS recently but decided it wasn’t my style. I currently have machines with Manjaro and various Ubuntu distros, Windows and Mac OS.
Where do I fit on your scale?
Anycubic offers them as an add-on for their printers for under ~120€ when purchased with the printer. That’s a reasonable price. But buying them on their own the ~200€ price is a bit much
