Windows for a long time before I knew what OSes were. I never liked how locked down MacOS is so I’ve never used that. Then I tried Ubuntu in college, mostly to play with. Then tried Arch, fucked up my system a couple times and reinstalled, then tried Manjaro because I’d heard it was more stable and less fuss. And now I’m back on Arch. I think I’ve finally mostly figured it out over the last decade lol, I haven’t had a problem with my install in years.
