Which is better MongoDB or firestore?

What are the differences between Firebase and Firestore? Firebase is a more compressive solution vs. Firestore and incorporates multiple services like databases, notifications, analytics, ML, etc. Firestore is a NoSQL database that is part of the Firebase app development platform.

MongoDB has the ability to respond to requests faster than most other NoSQL databases, and it usually outperforms Firestore in processing read/write/update operations .

Cloud Firestore provides a programmatic interface for retrieving data based on “references,” with a SQL-like query syntax designed for asynchronous processing. MongoDB is a more robust document database known for high performance and best-in-class security , and has several advantages over Firebase.
