I guess it depends on where you're located and your budget. I've had a very good experience with Thinkpads. T480 with Ubuntu was a pleasure to use and you can get it almost anywhere in the world. Always get a pro-grade laptop, not a consumer one. Consumer laptops have hughe price competition, are difficult/cannot be upgrader.
