Dell Latitudes have been relatively painless for years with Ubuntu/Kubuntu LTS, probably because Dell sells a version with Ubuntu preinstalled. Still, Dell doesn't have fingerprint reader support in Linux, and the built-in card reader needed additional setup, but other than that it just works on a fresh install. Even my favorite Windows games work on Steam with Proton, if you accept minor texture glitches, which I gladly do to avoid dual booting.

I love it because these days I have less time to fiddle with it every six months.
