Our take— Gamma wins
Based on our comparison of published pricing, features, and compliance data, Gamma scores 8.0/10 to Sudowrite's 7.1/10. Gamma pulls ahead with GDPR compliance and SOC 2 certification. Sudowrite stays close but doesn't lead on any single attribute here. If GDPR compliance matters, go Gamma; if it doesn't, Sudowrite.
