Dunno about that. I have a Dell XPS 9350 - to get a stable wifi connection under Linux I had to pull the Broadcom wifi card out and replace it with a much nicer Intel one (good luck doing that on the 2018/9 model - it's soldered in).

For a couple of years, the internal NVMe drive wasn't supported unless you changed from "RAID" to AHCI mode - unknown performance and power effects. It looks like that's changed recently.
