Started on Manjaro but I was annoyed when they let their SSL certificates expired several times so I moved to EndeavourOS. Now I am using NixOS, and I probably stay with it for a while.

I’m guessing they’re distro hopping. People often jump from Manjaro to Endeavor to get a more clean Arch experience. This is what I did too, on my laptop a couple of years ago, and I’ve stayed on EndeavourOS since.
