Owning a Lenovo X1 Carbon 7th gen, 2019, 4K screen, 16GB RAM. extremely impressed with the hardware, running Linux Mint and going to move to Manjaro.
Initially i tried PopOS! but they removed from Gnome the intermediate scaling (1.5X) of the UI, just like in MacOS you have Display - Scaled options.
I really like the per monitor setting which you don't have in Linux. (or i didn't research enough); e.g. More space on main display (external 4k monitor) and Larger Text on the macbook screen.
I'm also jumping ship due to the worst experience i had in 25 years dealing with technology, 1 month to replace a swollen battery with a 3rd party repair service. Apple throws now all this "complex" hardware issues to 3rd parties since their employees are pressuring them not to execute hazardous repairs in their own "centers"
