Hello,
I asked myself the same question when I started using multiprocessing
time ago. So I was very happy when I saw the question by James.

From my limited knowledge, I would say that a Manager can be useful
when processes are distributed across different hosts, or if the
exchange of information between processes is more complex than just a
couple of synchronization primitives.

Best
