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.
Installed an early version of Slackware on a 386 in the 90’s. Went through a couple it jobs so I ran windows for a bit until 2002. I had bought a nice laptop and it came with windows xp. Xp was so bad after windows 2000 that I had to find something else. Played with redhat and a couple other dostros then went back to Slackware and have been on it ever since.
It’s funny you mention xp being so bad, I’ve always remembered it as the one people loved. But I was using MacOs 9 in the school computer lab while xp was getting reamed for its ui and early security issues so.
