Not the parent, but I would. We've been using NATS for about five years at my company, and we recently adopted JetStream, and have been really impressed with it.

NATS, especially with JetStream now, is a Swiss Army knife of messaging. It can do RPC, Kafka-type batch streaming, low-latency realtime notifications, large-scale network transfer, offline sync, work queues, mirroring, weighted routing, partitioning... it's incredibly flexible. The simple but powerful primitive you have around subject routing/mapping/transforms, stream placement, replication, offline lead nodes etc. are just fantastic. It's super reliable. It scales from tiny apps to huge ones. The CLI and API tooling around streams and consumers is also fantastic.

Everything just feels well-designed and sensible. The new key/value store and blob store (both built on top of JetStream as client-side abstractions) are also super neat, and we've started using this functionality.
