## What the models said about Neon

- "Supabase or Neon (both serverless PostgreSQL) stand out as the best managed relational database services" (Grok 4.1 Fast, budget prompt, first choice)

## What the models said about Azure SQL Database

- "Azure SQL Database, while generally robust, has resource caps and licensing implications that require careful planning" (Mistral Small, negative prompt, soft negative)
- "Standard Azure SQL Database strips out many legacy features (like SSIS, SQL Agent jobs, and certain system views)" (Qwen 3.7 Flash, negative prompt, soft negative)
- "These are solid managed services, but Azure's own guidance warns not to choose solely by engine compatibility" (Perplexity Sonar, negative prompt, soft negative)
- "Azure SQL Database is a fully managed, intelligent relational database service built on the Microsoft SQL Server engine" (Perplexity Sonar, comparative prompt, first choice)
- "Amazon RDS or Azure SQL Database would be the safest bets depending on your existing tech stack" (MiniMax M2.5, paraphrase prompt, first choice)
- "Best for Microsoft Shops ... Lower first-choice share (4%) in general recommendations, but very strong within Microsoft-centric environments" (Kimi K2, direct prompt, alternative)
