For quality and reliability. This is astonishingly subjective and quite probably wrong :p
1. Thinkpad. Not as good as they were, but appear to be trying to improve again. Usually a fairly safe bet for BSD & Linux drivers. Support (UK) have been excellent.
2. Dell 2. HP (Like with Lenovo separate the cheap consumer crap, and the well made professional ranges)
3. The rest
4. Apple. Well made, hopeless for upgrade, now very overpriced. New keyboard seems to be disliked on reviews so far.
99. Acer - Pet hate brand that always seems to have far more than fair share of issues, and support (UK) terrible.
No experience of clevo or system76. Not sure MS have been around long enough with Surface to judge well yet. Personally I would be wary of Razer, though I've not owned a laptop of theirs, which might be superb. None of their mice and keyboards seem to last 5 minutes. Santa will bring the kids no more Razer Nagas.
