Honestly, switching to Garage Band from Audacity for my podcast was a game-changer in the editing. I can do it so much faster with the tools that are available in editing--especially when you are dealing with more than one track to edit. I also think Garage Band could be fantastic for recording a whole album initially before sending it to be mastered elsewhere. And I think Garage Band could be perfect for sync music licensing because it's still relatively easy to use!
GarageBand has just a few clunky settings--otherwise, it is a very user-friendly program with lots of functionality. Beginners can get started pretty quickly with the program, while more advanced users can dig around and find plenty of other tools to use to tweak things within a recording or editing session
Because GarageBand is included on macOS and iOS purchases, and we already use an Apple environment at our office, it was an easy decision to go with the 'free,' included program for our basic audio editing needs. We did also purchase Logic Pro X, since it is the 'big brother' to GarageBand, but our volunteers tend to use GarageBand first because of familiarity and ease-of-use
