MongoDB gets a lot of hate and created a bad reputation for itself by way of a very successful marketing campaign where they convinced a whole lot of companies to replace whatever RDS they were using with MongoDB some years ago. This caused a lot of RDS-driven applications to uh, experience a lot of development issues. It basically never makes sense to drive an application with MongoDB, which is why a lot of folks think it's strictly worse. A perfect MongoDB (or any document db, really) use case has zero relationships. This is accomplished by duplicating data across documents where you would normally use a foreign key in an RDS. Naturally, this is anti-pattern for RDS-minded folks and everything you'd want to do with Mongo stems from this mode of thought (preprocessing/data replication instead of lookups). Personally, I've had great success with Mongo and appreciate it for it's incredible depth in text searching via Atlas Search. Surprisingly, the web interface for Atlas in general is actually quite good and it's the only one I can bear to use; I usually can't stand them.
