Github edges out Sourcegraph modestly on homepage messaging, 83 to 74. Here's where the gap comes from.

Github is clearer about what it does (100 vs 59 on clarity). Github's hero ("Search code, repositories, users, issues, pull requests...") names something concrete, while Sourcegraph's ("Code understanding for humans and agents") stays abstract. Sourcegraph is better at saying who it's for (ICP: 79 vs 53). Sourcegraph's targeting is crystal-clear, while Github's is decent. Github has a much stronger pricing page (90 vs 70).

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