I have not had many issues in the past 15 or more years myself running Linux exclusively aside from a shorter Macbook period. Perhaps I have just been lucky.
We sported (in guessed cronological order of first buy): Dell, HP, Lenovo, Slimbook, Tuxedo, Starlabs, BTO all running Linux at our company. We have not had big issues with any except for keyboard on a Dell, Tuxedo, Slimbook and cooling on a Lenovo. Since I chose the Slimbook many have followed on the path of smaller suppliers and I think we rarely buy from the big makes now.
I have been very happy with slimbook. I came from a macbook (bad idea) with the bad butterfly keyboard and the slimbook was a big upgrade on that front. It’s still not the greatest keyboard for some but I do like it. I have been wanting to buy a new one but whenever something broke or was insufficient I could either upgrade (2 x nvmeSSD slots and RAM can be replaced) or they still supplied spare parts when I sent them an email (keyboard replacement after 4 years). I wanted a framework but Slimbook has offered me spare parts as needed for longerbtham could buy a framework and the slimbook still works well. Plus it’s less expensive. Replacement of the keyboard was not toolless requiring glue to be heated but I did manage to quickly do it with a sleepy head at night. I’d buy their new 13" if this one would be out of service. I’d buy one now but it feels such a waste.
Things I did not like 6 years ago: webcam and microphone of lesser quality, display nice and matte with good color rendition but lower resolution than I’d prefer, no USBC charging on USBC port. Display and USBC are resolved on the new models, no clue about webcam and microphone.



We have a few Tuxedo computers and some other Linux brands at our company and are generally happy about them. Cheaper devices have a less than perfect keyboard (though I liked the one on the slimbook) a worse camera and microphone (though some are very ok).
I’m very happy with these Linux devices. The few makes for which we needed parts also supplied them but sending the device their way for repair took longer than we’d have wanted.
