I'm off Lenovo X-s due to poor keyboards and poor warranty support. I was told (around the Gen5 era) that they often have slightly less powerful CPUs than similar competition though I have no idea if this is still true. They were also slower to offer better displays.
Onto Linux-on-Dell XPS 13 for a few years, though admittedly I didn't pay for it so I didn't really have a choice. Still, I'm happy and would easily recommend the product. A lot of firmware upgrades happen over `fwupdmgr` too.
The recently posted StarBook 14-inch looks interesting, but the screen isn't hi-res.
