I personally use a ThinkPad Z13 (all AMD; it's nice but pricey), but I'd recommend getting a Framework (which wasn't an option for me back then). I think modular and repairable laptops are cool, plus they seem to be well supported by the Linux community.
They don’t have a BIOS updater for Linux (yet) and they have a history of overpromising stable updates. I get they’re hamstrung by upstream providers, but it’s a bad look on them to basically deliver a promised Thunderbolt update 1.5 years after announcing it. The CEO did say at least that they’ve hired on a new development team to get things moving, so hopefully they’ll be able to catch up.
Everything else I’ve heard about Framework is stellar.
I've been watching on the framework machines for my next one. It looks like fwupd support them for BIOS updates. Framework owners will know more for sure.
