NATS has a bit more in terms of durability guarantees so I have found that it hits more use cases. I'm trying to strike a bit of a balance between "use the exact right tool for the job, even if that means you have 25 different services" and "just use Postgres". I do think Postgres/Redis/ClickHouse is probably fine as well but durable streaming would be hard to give up.
