Our take— Gamma wins
Based on our comparison of published pricing, features, and compliance data, Gamma pulls ahead with multi-factor authentication and a no-training-on-your-data policy. Leonardo.ai stays close but doesn't lead on any single attribute here. Gamma scores 8.0/10 to Leonardo.ai's 7.6/10. If multi-factor authentication matters, go Gamma; if it doesn't, Leonardo.ai.
