Generally the best laptops for Linux are popular models from popular companies and are at least a year or so old. Very few vendors go out of their way to ensure that all their devices and peripherals work AND ensure the appropriate userspace packages to use them are in the appropriate places when the laptop makes its debut. All of that has to be done by the folks actually trying to install Linux on the laptop, and that takes some time.

You will generally never go wrong with a popular Thinkpad (X/T/P series) that was released a year or more ago.
