Best is Framework in every regard. Works 100%, great Linux support, specify exactly what you want and it’s fully repairable. (They’re also by far the most satisfying machine to unbox, given you have to plug it all together yourself)

Lenovo and Dell are okay, in my experience. The odd thing but generally fair quality hardware and reasonably compatible. (Thinkpad quality isn’t what it used to be, so don’t pay a premium thinking it’ll last, Lenovo are trading on its past glories)

Avoid HP - shoddy flimsy things now, and with a lot of bespoke drivers (graphics and audio, plus function buttons in particular)

There’s quite a lot of random-branded Chinese laptops around now. I’ve no direct experience of them, but I imagine they’re exactly how you’d expect them to be. Cheap, tailored for the OS they ship with, but will probably work to some degree. Linux is past its initial hardware problems (and to be fair, hardware is problematic now)

There’s another thread that’s a few years old, but still contains some useful info - such as “Check the Arch Wiki”

Thinkpad t480 with libreboot from minifree

Thinkpad X1 Carbon if you’re swimming in money and want the lightest possible laptop, Thinkpad T14 if not.

Asus Zenbooks are kinda neat machines too, and taiwanese instead of chinese, but probably not quite as reliable.

Thinkpad t480, they can be found pretty cheap second hand, then install libreboot. Can be upgraded with 64 GB of ram and a 4K screen.

They’re a bit expensive up front, but I’m really enjoying my Framework.
