Linux Furs

I would say generally most laptops from big brands will support Linux and run it very well, in most cases better than Windows. As for what model or brand you want that really depends on what kind of work you're going to be doing on that laptop, as well as how futureproof you want it to be.

I ended up getting an Oryx Pro 5 from System76 since I play a lot of games and also use GPU intensive software (3D modeling, GPU computations, etc). This computer fit my needs though this computer might not necessarily be for you and your needs.

Honestly most laptops should work out of the box now. Based on good experiences people had with Gentoo and the WinMax 2 (2022), I preordered a WinMax 2 (2023) and will be moving my current desktop (TigerLake Engineering Sample Franken computer) to home server use. Had I not gone this route, I would have probably gone either the StarLabs Starbook or the FrameWork route.

You can check out https://www.tuxedocomputers.com/. Their computers are designed with Linux in mind and come pre-loaded on Linux. Plus they're all modular, so you can actually take parts out and replace them if you want.

Avoid anything ultrabook for serviceability and upgradeability. System76 is also always an option. I'm personally biased towards the Thinkpad T-series. Avoid the E series because theyre just bad, and avoid the Yoga series because they are hard to service.

I love my T420, but I do not recommend it unless you can deal with a TN 768p panel (I.e. shitty) or you really like modding your stuff.
