Hi,

The custom object name and standard controller name are the same. If you use the standard controller then sharing rule and other standard salesforce behavior related to that object will be applied to your code.

 

However there are lots of scenario where you just not need any standard controller and need custom logics like calling external Web service or any other calculations / validations or you dont want to apply the sharing rules, then in that case the custom controller will be needed.


For example : you want to create the wizard like interface then you can use custom controller.

 

 

Also please see the question number 69 and 70 in below link
