my most recent purchase came from kfocus. i cared mostly about price, screen brightness, speaker quality and future proofing, so the macbook air was the price & spec combo benchmark to meet (future proofing is automatic with linux companies) and kfocus's 14-inch blew them out of the water (they don't anymore). the other companies wouldn't share information on brightness and speakers at the time i was shopping for a new laptop almost a year ago; but all are built on top of either tongfang or clevo base systems (for now) so future proofing is roughly the same everywhere with linux companies.

in the past i used system76 and tuxedo (tuxedo sponsored that video); i will buy from them again when it's time for a high end system. their low end systems are REALLY low, but the price tags for them are closer to midrange somehow; their low end laptops costed the same as the kfocus but with much weaker & missing specs. (i assumed that they didn't share the missing specs because they were too weak).
