## What the models said about Snowflake

- "Snowflake — bills by credit-hours of uptime; it gets expensive fast and is poor value for small marketing workloads." (DeepSeek V4 Flash, budget prompt, hard negative)
- "❌ Snowflake: Minimum warehouse costs make it expensive for low-volume marketing analytics" (GLM 4.7 FlashX, budget prompt, hard negative)
- "Avoid for tight budgets: Snowflake/Redshift (higher baseline compute ~$300+/month)" (Grok 4.1 Fast, budget prompt, hard negative)
- "Snowflake: Best for most mid-market B2B companies due to excellent performance with structured data, strong security, and predictable pricing" (Mistral Small, paraphrase prompt, first choice)
- "Warehouse: Google BigQuery (if your web analytics is GA4) OR Snowflake (if you want a neutral cloud platform)." (Gemini 3.5 Flash, scale prompt, first choice)
- "the most common stack is something like BigQuery or Snowflake for storage plus Hightouch or Census for activation" (Perplexity Sonar, comparative prompt, first choice)

## What the models said about RudderStack

- "RudderStack (Avoid for Pure Marketing-Led Teams) ... RudderStack is not the right tool." (Gemini 3.5 Flash, negative prompt, hard negative)
- "overhead for pure reverse ETL (weaker dedicated features); event-volume pricing adds costs" (Grok 4.1 Fast, negative prompt, soft negative)
- "If marketing needs any level of self-service, this is a poor fit." (DeepSeek V4 Flash, negative prompt, soft negative)
