I've installed Arch on XPS 13 9350 and was also surprised by the amount of things that worked out of the box: touchpad, HiDPI scaling, different scales for different monitors, no issues with the Thunderbolt dock. Actually Windows had more issues for me on this laptop. Or course one can still screw something up but with a little effort it's easy to learn how to get out of trouble. Additionally Linux is like Lego - one can create their own setup, e.g. currently I'm using Yubikey's OpenPGP card to unlock full-disk encrypted disk. Bitlocker cannot use smartcards (but can use TPM).
