Arabic speakers : Can you understand most dialects well?

I can understand most dialects especially the Gulf and the Levantine Arabic. North Africa is ok I can just about understand Egyptian and Libyan , but the Moroccan and Algerians are extremely difficult imo, I can't keep up with what they say. I would say the Egyptian sounds slang, the people from the Levant pronounce the words very softly and lightly which is opposite to how the Gulf speak, they usually pronounce Arabic words heavily.
