The term "compare" is ambiguous. If you want to compare for *identity*, you use "is". If you want to compare for equality, you use "==". In most cases with None you are interested in identity, not equality. It's that simple. As I said, the archives have extensive discussions about this with lots of the nuances already covered in far more detail than I'm going to do again in this thread.
