Does laptop brands have nothing to do with how good a laptop is?

Aren't all laptops built with the same thing inside? Like for a basic laptop, Intel and NVDIA are in all of em.(The same versions of them) Doesn't that mean their exactly the same (Saying the memory and specs are same) or is their another part of the laptop that makes em different?

All opinions appreciated.
