Well, MongoDB was designed and created as a document database first and foremost, not an SQL one (NoSQL). It is focused and optimized for this particular use case and a way of storing and accessing data. PostgreSQL on the other hand, is a relational, SQL database that later on added support for composite column types like JSON/JSONB, ARRAY and others. Over the years, it has extended and optimized storing JSON documents in its own binary JSONB format, as well as added more ways to index, query and modify data of this type.
Expectedly, two DBs are significantly worse at inserting larger documents, but performance is again very close - slight edge for Postgres with 2213 inserts per second vs 2171 for Mongo.
