I just recently broke down and picked up an X1 Carbon 4th gen in lieu of a new MBP w/ TouchBar. The 14" display is a sweet spot for size and resolution. I run Fedora, and everything 'just worked' besides the fingerprint scanner. I'm sure the new XPS will have good battery life, but the X1 is doing amazing with minimal powertop/tlp tweaking.
What I couldn't find when I was researching were thermal reviews on the X1 Carbon (important to me). Thankfully, I can say that it's always cool to the touch and the fan rarely spins up enough to be audible. Naturally, building from source and some video do cause the fans to engage, but they're not 'whiny'.
