The short version

Each has a real cost: Azure SQL ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions; RudderStack on the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
They diverge on capability: Azure SQL covers Intelligent Performance, RudderStack covers Data collection.

Where each one falls short

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

Azure SQL

Ecosystem lock-in limits flexibility compared to open-source or multi-cloud solutions
Managed service reduces control over database configuration and optimization tuning
Pricing complexity with consumption-based model can be unpredictable at scale
Less operational depth compared to Amazon RDS for advanced scaling scenarios
Azure PostgreSQL is less compelling than dedicated PostgreSQL providers outside Azure ecosystem

RudderStack

On the free plan data processing stops after a second consecutive overage rather than being billed, so exceeding 250,000 events twice breaks the pipeline
The free plan allows 250,000 events a month
Growth starts at $265 a month for 1 million events, with volume sold in tiers up to 25 million
Overage is charged as the gap to the next tier's price rather than per event, so a small excess costs a full tier step
