I have the very old KDE Slimbook I from around 2017, and am very happy with it, built quality is very decent, well it is 7/8 years old now and still working nicely. Also have good experience with their support. PSU in the laptop died when it was about one year old because of lightning strike and electricity surge and they replaced the PSU without any questions and cost (except for shipping). The only thing I miss with my laptop is better keyboard, and more sturdy screen hinges. But yeah other then that. I can only recommend Slimbook.
I am using Tuxedo laptops since a few years now and it was always a pleasure to use them. Slimbook and Tuxedo are using barebones from Tongfang and sometimes Clevo in different configuration. I guess the build quality is almost the same for both of them.
