I have had an s76 wild dog which was amazing for an 11 year run, and I just replaced that with a meerkat. I also have a thelio which has been flawless. System76's desktops are amazing.

In 2013 I bought a darter and it's the worst laptop I've ever owned. I went through 4 keyboards and still it doesn't work, also the wifi radio is under the keyboard and you get a 50% signal reduction when typing. It had one of those trapdoor Ethernet ports which broke, so I basically became a dead device. That is an old metric, but it scared me off from buying laptops from them until they get their own hardware pipeline for them.
