## What the models said about Default

- "Default is repeatedly recommended for mid-market inbound routing + scheduling automation." (Muse Glimmer 30B, direct prompt, first choice)

## What the models said about Salesforce Lead Assignment Rules

- "Your CRM’s native routing (like Salesforce Assignment Rules or HubSpot Workflows) distributes leads sequentially but lacks the intelligence required for a scale-up." (Gemini 3.5 Flash, scale prompt, soft negative)
- "Limitation: Limited to simple property-based assignment; no availability checking; no deduplication before assignment" (Kimi K2, comparative prompt, soft negative)
- "Powerful but steep learning curve... is overkill/expensive for most mid-market unless you have dedicated admins." (Grok 4.1 Fast, direct prompt, soft negative)
- "If you use Salesforce, test whether its assignment rules and automation cover your actual cases" (GPT-6 Luna, scale prompt, first choice)
- "native workflows inside HubSpot or Salesforce are the right place to start since round robin and field-based logic are already built in" (Claude Haiku 4.5, comparative prompt, alternative)
- "The built-in starting point for assigning leads to users or queues... more intricate routing can require custom workflows or code." (GPT-6 Luna, comparative prompt, alternative)
