My Dell Precision 5530 for work is kinda meh - by which I mean it works most of the time, but the fact that it doesn't work every time is fairly big deal at this point.

My personal ThinkPad E495 has pretty much flawless driver support.

Granted, I'm running different distros (Ubuntu on the Dell, Solus on the ThinkPad) but the fact that the Dell Precision is certified specifically for Ubuntu is pretty disappointing.

I had two dell XPSes in 2015/16, one of which shipped with Ubuntu, and they were by far the worst compatibility experience I've ever had with a Linux laptop. I loved the hardware, but my God was the firmware garbage.
