I'm using the Thinkpad X1 Carbon 7th generation and I feel like with the latest Ubuntu 20.04 LTS it's finally at the level of usability I want in a Linux laptop. Everything works out of the box, including the speakers, camera, microphone, wifi & bluetooth, and fingerprint reader. I can even use my fingerprint for sudo! (I did have to run one or two commands to get that working though). The trackpad is also great, if a little small. Probably comparable to the Dell's. Also haven't got a chance to test real-world power consumption because I'm stuck at home lately (thank COVID for that) but it seems to be okay.
