I don’t really care.

I’m telling you why I am skeptical of any tech that intentionally obfuscates trade-offs, I’m not making a comparison on which of these is worse; and I don’t really care if people take my anecdote seriously either: because they should make their own conclusions.

However it might help people go in to a topic about performance and reliability from a more informed position.

I don't doubt your experience. But I think it might have been more just that guy, than NATS in general.

The other day i was listening to a podcast with their ceo from maybe 6 months ago, and he talked quite openly about how jetstream and consumers add considerable drag compared to normal pubsub. And, more generally, how users unexpectedly use and abuse nats, and how they've been able to improve things as a result.
