RabbitMQ shines when you need complex queue routing based on keys or headers. Instead of baking the logic to the app you can offload the routing logic to rabbitMQ. Same is true for NATS and Kafka.

I must say that rmq in k8s, is possible but hard to admin. It’s not a “toy”. But has great documentation. Will take several iterations to key in the right configuration for the use case.

NATS and Kafka can handle higher volumes on the same resources but IMO the use cases are different or you have to write lots of code app side to implement what rmq does with these tools.
