A site may have a use for a type of page that is more structured than the free-form Basic page. If a site has multiple pages with the same format, these pages will probably be easier to maintain as instances of a specialized content type rather than a Basic page. In a nutshell, it's a page template.
For example, say Human Resources has a page for every type of insurance that is offered as part of the University's benefits package. Each of these pages is similair: there's an intro paragraph, a section about elegebility, a section with a table of rates, and a section of supporting documents such as form PDFs. This would be a good case for a custom content type.
