Fast Mutalisks allow you to potentially do significant damage to the opponents economy, especially if the spire does not get scouted and no air defense is set up in time. Mutalisks also grant easy map control and usually let you take a 3rd base without much trouble while denying your opponent more than 2 bases. If you fail to do any damage to the opponents economy you should still have map control and use that to catch up or get ahead in terms of economy.
