What is the difference between EventStream and pub-sub?

Pub-sub subscribes to a named topic, as opposed to a message type in eventstream.
So let's assume you're monitoring a bank transaction, the topic name might be the transaction ID in a pub-sub system. When listening to the eventstream, subscribers would need to manually filter or correlate the various messages they're subscribed to by the transaction ID property on the messages themselves.

Just to add, as far as I understand from the code EventStream is local to a member in a cluster.
Pub-sub is cluster wide, so the messages are propagated to all cluster members.
