As someone else mentioned the framework pro is a good pick and also the cool new kid on the block with the repair and upgradablity(however you spell that). However spec and build quality wise, any high end business laptop will have full linux support since their be used for IT/software dev and robust enough construction to not break in a few years

That Dell looks good, ive heard good things about the new Lenovo too, really just go with whichever option is cheaper
