My take
Why I use MongoDB
When the data really is document-shaped - nested, evolving, schema-flexible - MongoDB earns its place. Atlas takes the operational pain out, and aggregation pipelines are powerful once you internalize them.

Honest assessment
Strengths & tradeoffs
No tool is perfect. Here's what shines and what to watch for.
Strengths
- Flexible schema supports rapid iteration
- Horizontal scaling via sharding
- Aggregation framework for analytical queries
- Atlas managed service is excellent
- Native Atlas Search and Vector Search
Tradeoffs (honestly)
- Joins are awkward compared to SQL
- Schema-on-read requires application discipline
- Transactions are slower than relational alternatives
- Easy to design schemas you regret later
