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
Perplexity
- Context window has been stealthily reduced despite prior claims of 1-million-token capacity
- Citations sometimes point to irrelevant or overly general articles that do not support the stated claims
- Weak performance on complex multi-step reasoning and deep logic compared to dedicated reasoning LLMs
- Web crawler ignores robots.txt directives and scrapes content from sites that explicitly opted out
- Pro subscription quotas and feature access quietly reduced without user notification
