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 have installed Ubuntu in I think at the beginning of 2020 at the end of my first semester as dual boot, because I wanted to learn it a bit while studying engineering informatics. Later I have installed it as my only distro on my Laptop to have more reasons to learn it since I use my PC mostly for gaming. After some time I was so confident with it that I wanted to try something new and installed Garuda on my PC and learned about proton. Then I learned about how many games I can actually play with it and used it as my daily driver for about half a year. Then I was distro hopping frequently, trying pure Arch, Gentoo and Void, wiped Windows completely at the beginning of 2022 because I didn’t use it anyways if I remember correctly and sticked with Void since about mid 2022 until today for my Laptop, PC and Server.
