For NoSQL, I currently use MongoDB and Elasticsearch in production. Elasticsearch was by choice, whereas MongoDB was something I inherited.

For new projects, if I'm picking NoSQL at all, I'm more likely to lean Elasticsearch, but it definitely takes longer to set up and has a much higher learning curve. And as always, it's going to heavily depend on the data and its access patterns. My default continues to be RDBMS unless there's a good reason not to, even though at this point, I actually have more experience managing MongoDB and Elasticsearch clusters.
