I'm not sure comparing them like this really makes sense. There were/are hundreds if not more different movements who consider themselves communist and that have (often radically) different ideas on what communism actually is. National socialism is a single party ideology and that party was only in power for a few years in a single country. Just like with communism there are/were many more "benign" far right or fascist movements.
