A local container is local to the job, is a property of the job, and has no visibility outside the job. Its function is to hide some of the complexity of the design.

A shared container contains a re-usable sub-set of a job. It can have its own parameters. It is stored as an independent component in the Repository.

Shared containers and shared routines tend to perform totally different tasks. The right one to use is the one that is appropriate to the task.

Basically its the scope of the container in the design, If you create a local container( A logic that reapeates inside a job multiple times) that could be used inside a job.Whereas the Shared container can be used accross the jobs ( a generic piece of code that could be used across jobs), This is the difference . apart from this the functionality remains the same for both.
