Framework. I've run Debian, Fedora and for a while now NixOS, all of which have worked flawlessly.
I did have to replace the heatsink/fan part on mine because the fan bearing started clicking, but I'm sure that was just a first generation product issue (I was one of the first batches). I was glad to be able to do the replacement myself at relatively low cost and the process couldn't have been easier (took about 30 minutes).
My previous machine was a 2013-ish ThinkPad X series and the Framework absolutely blows it out of the water. I'm looking forward to upgrading mine to a Ryzen motherboard sometime in the not so distant future.
You might be interested in setting up network bound encryption via Clevis and Tang. I use a hidden pi zero in my house acting as a Tang server. It's great being able to reboot any of my encrypted servers without having to manually unlock disks.
