I came across tuxedo computers randomly one day, and gave it a shot. Very impressed, and am extremely happy with my tuxedo pulse 15 gen2 - running their supported version of Ubuntu+KDE, that just works out of the box. Only thing I can complain about is that: speakers are not great (but I use headphones 90% time anyways), and KDE doesn't support independent resolution scaling (I need 125% for laptop display but 100% for external monitor), so it's a bit hacky to get scaling the way I want. However, everything else runs perfectly and smoothly.
It's best laptop I've ever owned for linux. It is quite, portable, moderate power laptop, for fair price. I gave my wife my Macbook air M1 over this one. While the M1 CPU/GPU is a little more powerful than Ryzen 5700U (8 core), I get more ram (32gb 3200mhz), bigger and faster disk (1TB 980 pro pci 4), more battery life (18hr idle, 10+ working) for similar price. It's also repairable, w/ removable standard components (not cpu tho). Linux running SMOOTH.
Basically with these type of vendors, you don't need to struggle or sacrifice (much) to run linux anymore. Tuxedo computers [1] has many more models worth checking out, like with high end GPUs or smaller/more portable (even one that support external liquid cooling and an rtx 3080ti lol).
