I know about Tuxedo but they have not been up-to-date for a long time. I checked their website and I can finally see the improvement in their newer laptops. But for a long time there were no laptops with USB 4 (e.g. Thunderbolt), only ISO keyboard layouts (bleh) and many other obvious and annoying drawbacks.
Also, Tuxedo still feels like brand of white label products. I know System76 is sort of the same, but somehow their products feel like products. But maybe it's just the marketing.
