@@IDENTITY could be wrong if you have a trigger on the table. If you want it explained in detail, then I'd suggest searching this site for the many articles and threads that discuss this topic.

@@identity is global. When you ask for @@identity you might get an identity value that was inserted in another statement/stored procedure while scope_identity always gives you the last identity in the current scope. Therefore you shuld always use scope_identity...
