Scipy edges out Numpy modestly on homepage messaging, 38 to 32. Here's where the gap comes from.

Numpy is clearer about what it does (46 vs 15 on clarity). Scipy has stronger CTAs (80 vs 0). Scipy is better at saying who it's for (ICP: 45 vs 15). Scipy's targeting is decent, while Numpy's is generic. Scipy has a much stronger pricing page (65 vs 0). Numpy doesn't have a detectable pricing page at all.

Both sites use the "Community / Movement" positioning archetype — they're competing on the same narrative, which means differentiation has to come from execution, not framing.
