I tested many distributions of linux pclinuxos was my first choice I have always like it. It had issues with firefox plugins so I than tried Ubuntu never liked unity or the gnome GUI. was always slow and cliches on the graphics so than tried Linux mint 17 back than never now have a Thinkpad t520 with linux mint 18.3 cinnamon runs better than windows 7 did which came with the laptop. Hint ThinkPads are a great options for linux OS if you are looking for a good option.
