Where each one falls short

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

MongoDB

16 MB maximum document size limits large single objects
No native JOIN support for relational data operations
Higher memory usage due to storing field names with each document
Eventual consistency in distributed deployments can cause data stale reads

Neon

Compute pricing at $0.106-$0.222/CU-hour means costs scale directly with workload, unlike fixed-price alternatives
Separation of compute and storage may add complexity to cost prediction compared to all-in-one plans
