My laptop (my only computer) is pretty old and was getting slow a couple years back, I had a theory that Linux would run a bit better, it didn't change much but I got used to Ubuntu and have enjoyed it after learning some commands, how to find my way around, etc. I don't really have any interest in going back to Windows.
This being said, I don't play many games, mostly just Binding of Isaac these days, so I've yet to run into any compatibility issues.
