A detached garage is only permitted to have one circuit run to it. Therefore if you want multiple circuits (AC, lighting, power tools, general purpose receptacles, etc.) you need a sub panel. If the garage was attached then you could run all the different circuits from the main panel.

Agreed. If you are making the effort this is the way to go. A 60A sub panel generally covers most expansion.
