What OS do you use on your pc and why?

My desktop PC is Windows 11, I've tried setting up dual booting but it never worked properly (probably because I wanted to have separate SSDs for each OS) so I just use Virtualbox if I need a different OS on there. I also have a laptop whose OS I change depending on what I need (generally Fedora, Win 10, or Debian) but I am considering shelling out for a Macbook as well.

I don't like committing myself to one specific OS.
