I have two. Personal: Thinkpad P51s running Ubuntu 16.04. I also have the big 72wh secondary battery. I'm one of only a few people at conferences not looking for power by 2pm. Work: Dell precision 5530. It came with Ubuntu 18.04. the extra work Dell has done to make all drivers/hardware working is great. Everything just works out of the box. Even my Thinkpad required a slight amount of tweaking.
