As I said in my first post, I understand that all three ways are correct. I just wanted to know "the best", which means that it should always give the same results and should not be deprecated in the future. If I understand you correctly, "=None" is most recent implementation of "is null" and (for me) it seems more natural. Thank you for your answers!
