All of those are similar systems and have persistence. I'm not sure what distinction "streaming" makes but they also all support multiple publishers and subscribers. Some only use local storage on the nodes while others can tier out to cold storage like S3.

MongoDB is a full OLTP document store so it won't match the write throughput and pubsub features of these focused systems. RabbitMQ on the other hand has performance limits but is meant for complex service-bus style routing and RPC uses, but I recommend using NATS for that now.
