Currently using a T14 gen2 amd with 5850U and 32g of ram. Performance is excellent. The battery life is also excellent, unless you get the 4k screen in which case it's not good (I have both). I'm waiting for newer amd options really: I'm extremely satisfied with the vega performance, and stability has been excellent under linux. Compared to the issues I had with the intel xe drivers under linux I'm not willing to go back really.

I would consider the M1 Pro if it had complete linux support. However I do prefer the lenovo keyboard, and I also generally like the "boring" chassis of the lenovo as well. The x1/thinkpad chassis is extremely durable and forgiving. If you travel with your laptop you don't need to worry about handling it like it's made of glass. I cannot count the amount of dinged or bent macbooks I've seen due to the alu chassis.

System 76 is not really competitive in EU last time I checked due to customs.

I know framework only recently has opened resellers in germany/france so it wasn't an option when I was looking at the time. However I don't see much appeal at the "upgradability", aside from the battery and ssd (which is easily serviceable on all lenovos). I always bought the laptop maxed out to avoid upgrading/incompatibility issues and used the laptop until it finished it's service life (5+ years).
