## What the models said about BigQuery

- "I wouldn't automatically avoid BigQuery, Snowflake, or Redshift... BigQuery charges for query processing... careless or frequent queries can affect the bill" (GPT-6 Luna, negative prompt, soft negative)
- ""BigQuery is built for speed and scale, but marketing teams often discover its limitations only after months of custom pipeline work. Query cost spirals."" (Muse Glimmer 30B, negative prompt, soft negative)
- "Query cost explosions: Exploratory queries on 1TB+ tables without partition filters can cost $50–$200 per run" (DeepSeek V4 Flash, negative prompt, soft negative)
- "the most practical stack is usually BigQuery + self-hosted Airbyte + dbt + Metabase, with BigQuery as the warehouse" (Perplexity Sonar, budget prompt, first choice)
- "BigQuery is often the default choice for modern marketing teams because of its deep integration with the Google ecosystem." (Gemini 3.5 Flash, comparative prompt, first choice)
- "Most marketing teams today pair BigQuery (for Google ecosystem) or Snowflake (for multi-cloud flexibility)" (MiniMax M2.5, comparative prompt, first choice)

## What the models said about Snowflake

- "Avoid Snowflake and enterprise ETL tools" (DeepSeek V4 Flash, budget prompt, hard negative)
- "General Purpose Warehouses: (e.g., Snowflake via partner templates) — More control, harder setup, higher engineering overhead." (Qwen 3.7 Flash, scale prompt, soft negative)
- "Snowflake lacks a permanent free tier (only 30-day trial), making it less ideal for long-term budget use." (MiniMax M2.5, budget prompt, soft negative)
- "Snowflake + dbt Cloud + Hightouch is the most generally "best" marketing data warehouse + reverse ETL stack for a mid-market B2B company." (GPT-5.4 mini, direct prompt, first choice)
- "Snowflake is ideal for mid-sized B2B companies offering scalability, cross-cloud flexibility, and strong marketing platform integrations" (MiniMax M2.5, paraphrase prompt, first choice)
- "Snowflake is the most popular for mid-market B2B companies due to its ease of use, strong performance, and excellent integrations." (Mistral Small, paraphrase prompt, first choice)
