Ask HN: Have you ever chosen Postgres over Mongo and regretted it?

The past 2 years seem to have been the death knell for Mongo and the "NoSQL" hype, with Mongo moving toward SQL parity and SQL databases supporting JSON storage, like Postgres with JSONB. At this point it seems that there are very few workloads for which Mongo is the best option compared to Postgres+JSONB. I'm wondering... 1) Have you ever chosen Postgres over Mongo, and regretted it ? Why? Did you end up switching to Mongo? Was it better? 2) Can anyone name a use case where Mongo is clearly a better choice than Postgres+JSONB?
