I've used NATS before, and I might not have explored all the options, but what I used it for was a pub/sub model of messaging. I cannot speak to performance of NATS as we used it in low-traffic / low-demand setting. In terms of convenience, when used from Go, iirc, it offered some kind of built-in serialization (unlike eg. ZMQ, where you'd have to add your own). Debugging lost messages was painful, but I've never used a tool where it wasn't...
