I have a framework 12th gen. It's great. Fantastic build quality and when I want to upgrade, I don't need a whole new laptop, just the necessary internal components. I can even switch to AMD!
Coreboot is cool, and I can't wait to see the new system76 laptop that is being built in-house, but until that comes out, I don't think I would ever consider the current lineup of system76 computers.
My main motivations are repairability, upgradability, and specificity of components, and system76 just doesn't offer that. They don't tell you what ram or SSD models go into your laptop, they don't sell replacement parts, and there is no upgrade path.
