Feature-wise, it's about 3 years behind the features in ES. Although you have to pay for the higher tiers in ES, there's a much richer feature set. The Elastic cloud offering is much nicer than the AWS hosted version, for a similar price.

How can it be three years behind when the OpenSearch project is barely one year old?

PfSalter, are you able to quantify what is nicer and improved about the elastic-hosted version?

In my experience, OpenSearch remains largely interchangeable with ES and has been a relative pleasure to integrate and use.

The opensearch project was released a while ago as opendistro and was just renamed to opensearch a year ago [1]. As for features, it depends what you're doing, but ES upgraded to Lucene 9 6 months ago [2], and they've had document level alerting for at least two years.
