I believe (but I've not tried to verify this) that the network connectors should be used for bridging to another ActiveMQ broker (because they will use the OpenWire protocol and be more efficient) whereas the JMS to JMS connection should be used when the other broker is a non-ActiveMQ JMS broker.
The differences you'll see when using dynamically included destinations are basically what you've noted: 1) you don't have to know the names in advance (wildcard matching is available, though somewhat limited), 2) messages will be forwarded only when a consumer exists (because the disconnection of the last consumer results in that destination no longer being bridged, until another consumer connects), and 3) you have to enable advisory messages, since that's what allows the dynamic nature of the forwarding.
