A. It allows pages to perform mass updates of records.
B. It allows pages to perform pagination with large record sets.
The StandardSetController class also contains a prototype object. This is a single sObject contained within the StandardSetController class. If the prototype object’s fields are set, those values are used during the save action, meaning that the values are applied to every record in the set controller’s collection. This is useful for writing pages that perform mass updates.
StandardSetControllers have built-in pagination that helps reduce the number of records displayed on the page.
