I’ll go first, I took my mom’s college textbooks which came with discs for a couple distros and failed to install RHEL before managing to get Fedora Core 4 working. The first desktop environment I used was KDE and despite trying out a few others over the years I always come back to plasma. Due to being like 12, I wanted to run my games on it, and man wine was not nearly as easy to use (or as good) as it is nowadays. So I switched back to windows until around 2015 or so when I spent the next few years trying to replace windows as much as I could. Once valve released proton, I switched fully and have t looked back, unless my still there windows partition tries to take over my computer when I restart it at least.
I discovered Linux when I was learning programming in my childhood. I used it side-by-side with Windows all the way through college where I started daily driving only Linux. I hopped this order mainly: Ubuntu > Elementary > Debian > Arch > Gentoo > Arch > Fedora > Nix. Probably not right when I started programming in 2007 when I was 8, but before I was doing Arduino development at 11, so like 2009-2010ish. Started daily driving in 2018 or 2019
I never went back and forth as I wanted to get away from Windows ASAP since it’s such a terrible line of operating systems that do things the most backwards way possible. For a long time I was in the “I need to have Windows for my games” camp, which is why I maintained a dual boot or a computer with Windows installed, but then Proton happened, and there was no longer any need, and I could fully wipe my hands of that filth
