Our take— ChatGPT wins
Based on our comparison of published pricing, features, and compliance data, ChatGPT scores 8.7/10 to Kling AI's 7.0/10. ChatGPT pulls ahead with GDPR compliance and SOC 2 certification. Kling AI stays close but doesn't lead on any single attribute here. ChatGPT is the call when GDPR compliance matters — otherwise Kling AI.
