Github edges out Gitbook modestly on homepage messaging, 83 to 75. Here's where the gap comes from.

Github is clearer about what it does (100 vs 66 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while Gitbook's ("The AI-nativedocumentation platform") stays abstract. Gitbook has stronger CTAs (85 vs 60). Github triggers decision paralysis with 10 competing CTAs, while Gitbook keeps it focused at 14.

Gitbook uses a "Platform / Ecosystem" positioning while Github goes with "Community / Movement" — fundamentally different approaches to winning the same buyer.
