I owned several IBM Thinkpads, and one or more Dell (one XPS, at least). Thinkpads are definitely very well supported (at least, the high-end standard form-factor ones; I had an Helix, and the support was mediocre), and they would go first in my list of Linux-supported laptops. The Dell XPS 13 was working very well, AFAIR. I can't remember/find though, if I had other ones.
