I've had good experiences with the XPS 13's last two or so generations with Linux... I want to say with the 10 and 11-series Intel chips? I have an older, thicker XPS 13 that only ever ran Windows which never really gave any issues either, apart from its goofy side-bottom-chin webcam placement.

But I also had several coworkers with the same newer 11-series XPS machines who got a series of lemons... Dell replaced the motherboards, but still.

I've had a bad XPS experience, but I also have really good latitude 72xx and 74xx experiences.

I think that XPS build is just the wrong machine for Linux and like someone else said the wrong form factor for poor power performance management.
