I always get pooped on when I say this, but I didn't like 7. it brought the confusing libraries, ugly glass theme, and all computers I used it on, explorer (file manager, taskbar) crashed a lot and had to do win+r -> explorer.exe to get it going again.
I liked vista, but I only used it on my very first pc and for not much else but web browsing. I also liked 8.1, just needed to tweak it a bit, like replace that horrible start menu. I had instructions for myself for all kinds of registry stuff that needed to be done to a fresh install.
hated 10 from the beginning because it immediately seemed like it fights back too much, forcing microshit down your throat, and all that spying crap.
and finally when I saw 11....well, I've used mint for about two years now.
