It’s a single consistent place in the UI for:

* seeing the name of the app that is currently in focus
* discovering all commands / modes that can be performed / accessed in the current app in an organized layout
* discovering all default and user-custom keyboard shortcuts for an app’s menu bar items
* managing windows belonging to the current app
* searching the entire menu bar hierarchy via the Help menu
* accessing an app’s settings panel
* finding the app’s version number
* hiding or quitting the current app (or hiding all other apps instead)

also the Apple menu on the left edge has really handy menu items for quickly getting system info and force-quitting troublesome apps
