Ubuntu at the start of my college years, dabbled with Arch in the senior year. Huge learning experience, but ultimately I went back to Windows because gaming support was nonexistent at the time. Kept the dual boot up and kept it running Arch during the day for coursework, Windows when I was all done.
For the past decade since then I was entirely back on Windows. Aside from an Ubuntu VM for my last job, I didn't really get back into it until the Steam Deck launched a few years ago, and at the start of this year I decided to set up a dual boot again once I got a new full new desktop build. Tried Bazzite, really didn't like how restricted I felt, immediately wiped it and tried out CachyOS instead, and that's my daily driver today.
And just this past week I finally decided got into selfhosting, something I've been eyeballing for ages but never really got around to. Proxmox on the host, Debian VM, pretty standard and works amazingly.
