They diverge on capability: Marqo covers Semantic search, OpenSearch covers Full-text search.

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Marqo

Pricing not publicly available, enterprise sales-only model
Requires custom implementation and integration work
Limited to ecommerce use cases compared to general search
Model training requires sufficient customer behavior data

OpenSearch

Diverged from Elasticsearch since 7.10, so clients, plugins and features no longer map one to one
Operationally heavy in the way Elasticsearch is: cluster sizing, shard strategy and JVM tuning are ongoing work
Smaller ecosystem of third-party tooling than Elasticsearch, which most integrations still target first
Overkill for plain application search, where a dedicated search engine is far simpler
