By framing

Which of the six questions produced the naming. By model says how often; this says asked what. The first-choice count on the right carries the marks of the models that produced it.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Best low-budget pick: Microsoft Security Copilot—if your company already has Microsoft 365 E5 or E7.” GPT-6 Luna · AI SOC agents · budget prompt · first choice

“If your stack is fully Microsoft, this is the most seamless option—but it's more of a prompt-based assistant with growing autonomy” DeepSeek V4 Flash · AI SOC agents · comparative prompt · alternative

“Pick Microsoft Security Copilot or CrowdStrike Charlotte AI if your SOC already standardizes on those ecosystems.” Perplexity Sonar · AI SOC agents · comparative prompt · alternative

“Microsoft stacks (Defender/Sentinel) | Included in E5/E7 or ~$4/SCU-hour | Named agents for triage/phishing; scalable” Grok 4.1 Fast · AI SOC agents · direct prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“assists with queries but more copilot-like than fully agentic” Grok 4.1 Fast · AI SOC agents · comparative prompt · soft negative
