ZeroMQ is blazing fast, damn simple and battlefield proven. However it is also pretty low level.

Things like ACL, topic filtering or user management often need to be reimplemented on top of it. That is not the case for most MQTT blockers.

If security is a also a big concern for you, I would prefer an MQTT+HAProxy+TLS anytime to ZMQ with CurveMQ its home-made security.

The problem is retaining the messages until they get written to a database. MQTT only guarantees delivery to a single client with QoS 2.
