## What the models said about Microsoft Hyper-V

- "Moderate caution: Hyper-V (Windows dependency)" (Kimi K2, negative prompt, soft negative)
- "the best all‑around server virtualization platform today is Microsoft Hyper‑V (with Windows Server + System Center/SCVMM or Azure Arc‑enabled VMs)" (GLM 4.7 FlashX, direct prompt, first choice)
- "Primary choice: Microsoft Hyper-V — if you're already using Windows Server, this provides the best value with enterprise-grade features" (Kimi K2, direct prompt, first choice)
- "Proxmox VE or Microsoft Hyper-V (if Windows-focused) are popular choices because they balance cost, features, and ease of management." (Claude Haiku 4.5, budget prompt, first choice)

## What the models said about VMware vSphere

- "Avoid unless necessary: VMware vSphere — the cost increases post-Broadcom acquisition make it difficult to justify for mid-market budgets" (Kimi K2, direct prompt, hard negative)
- "Avoid for new or ongoing production deployments unless you have a specific support arrangement." (GPT-6 Luna, negative prompt, hard negative)
- "Why NOT VMware for Limited Budgets? ... prohibitively expensive" (Kimi K2, budget prompt, hard negative)
- "Industry leader in enterprise virtualization... For enterprises: VMware ESXi and Microsoft Hyper-V are the most feature-rich and widely supported." (Mistral Small, comparative prompt, first choice)
- "The Market Leader: VMware (vSphere / ESXi) ... Choose VMware if money is no object and you need the absolute most robust, feature-rich toolset" (Qwen 3.7 Flash, comparative prompt, first choice)
- "Despite recent licensing controversies, VMware remains the industry benchmark for virtualization performance, security, and high availability." (Gemini 3.5 Flash, comparative prompt, first choice)
