x1 (gen c5) is amazing as well. After almost a decade as a macbook user, i'm impressed by it & back to linux! :)
Btw if thinking of a X1C for Linux use, I'd skip the latest for now due to them changing how the sleep works and it having issues even with Windows (losing battery while sleeping). The fifth model is great though, if you're not looking for the 8th gen CPU and HDR screen.
