GPT

GPT-5 Mini

Prefers ChatGPT79 vs 21

“Based on the provided site content, ChatGPT communicates its capabilities clearly with concrete examples (full slide deck + speaker notes), visible features, and immediate demo outputs, making its value proposition easy to understand. Gemini shows strong technical content and Google-level backing but the pages shown include sign-in gates, 404s and 'unsafe app' warnings that reduce clarity and immediate trust for a general consumer.”

GEM

Gemini 2.5 Flash

Prefers ChatGPT77 vs 23

“ChatGPT (Company A) clearly demonstrates its functionality and capabilities through a detailed example of generating a presentation. Gemini (Company B), on the other hand, presents various error pages and shared-chat links that require sign-in, making it difficult to assess its core offering directly from the provided content.”
