DatastoreService - low level API. PersistentManager (JDO) - high level API that is based on DatastoreService.

Performance: DatastoreService consumes less resources, PersistentManager (JDO) - has some overhead.

Development: PersistentManager much more faster for development/support.

Another option that is promised to be faster in performance than JDO and faster in development than low level api - Objectify. This is new promising technology. Try it.
