I am confused. Isn't Jupyter Lab the same as Jupyter Notebook but also with a file chooser and some extra functions? I don't care a lot which one I'm choosing.

I am confused. Isn't Jupyter Lab the same as Jupyter Notebook but also with a file chooser and some extra functions? I don't care a lot which one I'm choosing. I always open Jupyter Lab because it has some very small neat additions. Why would I want to want to use Jupyter Notebook without the Lab interface around it?
