I got a System76 Serval WS laptop running Ubuntu 2 1/2 years ago and have been happy with it. I used it a lot pre-Covid when I was traveling more. It also updated well, although I always wait two months post-release before upgrading Ubuntu.
I bought a System76 Thelio desktop running Ubuntu in July, and I am typing on it now. I am very happy with it. One nice thing about it is I know the various parts of the system will have decent drivers for Linux. I did get an Nvidia 12 GB GeForce RTX 3060 graphics card with it - that is one area (Nvidia) where support could potentially be problematic, but I have had no problems thus far. The upgrade to Ubuntu 21.10 went smoothly. I also bought a 27" inch monitor with it, and working from home, it beats my old 19" inch monitor by a long shot, especially if I am doing git merges or something.
The first System76 laptop I bought was in 2014, and I have helped other people buy them, and I feel they have gotten better over time - the machines are better.
I like how much of the system is open, if I want to change something I can just drop down and do it - to the desktop layer, to the userspace level, to the kernel level. People have caveats, and I have run into them, but workplaces have had me run Windows or MacOS, and those systems have caveats as well. The ability to be able to look at the code and change it is something I like.
