ViewBag is a dynamic object while ViewData is a dictionary object.
ViewBag uses dynamic properties while ViewData uses string keys to store data.
ViewBag is a shortcut to ViewData['key'] while ViewData requires casting to access data.
ViewBag is not type-safe while ViewData is type-safe.
ViewBag is used for one-way communication while ViewData is used for two-way communication.

Accepted Answer

ViewData is more type-safe but may require more code for data manipulation and retrieval. The choice between them depends on the specific requirements of your application and your preference for type safety.

ViewBag is simpler to use but offers less type safety and may be prone to runtime errors if used incorrectly.
