Don't run Windows and you don't need fast. Unfortunately Linux on notebooks is always a dice roll of random features (cam, fingerprint, ..) not working.
There is a lot of older hardware running like crap because Windows just bloats up.
So is running MacOS on non-apple laptops or running windows on chromebooks. Preinstalled is another story, of course, you paid someone to make sure all those random features work.
That said, defaults seem often wrong and defaults matter. For instance, I recently got an HP Elitebook with an amd 7840hs because for some reason the _u version was tied to a lower res screen. By default it runs high powered and then the fan is loud enough to be annoying. Set it it to balanced or low power and the fan is inaudible.
