In my experience its been nothing but a dream. I had the same mint install on a asus zenbook prime from like 2012 to 2022. Battery went from like 5 hours on windows to 6-8 hours on mint. It was great. I do know that sometimes there are werid problems with some of the new "features" shipped in laptops. BUt I would say that looking up a particular laptop that you might be interested in and seeing what kind of linux support it has fixes that problem.

Or you could go 'built for linux' laptops. Librem, System 76, Framework, ect. Or Thinkpads. Those things are tanks and just work.
