Ehsan's Verdict

The gap between Stable Diffusion and Leonardo AI has narrowed significantly in 2025-2026, making the decision more context-dependent than ever. The AI image generation market increasingly values batch generation over style consistency, which shapes how these tools should be evaluated. My advice: trial both for 2 weeks against your actual marketing asset creation workflow. The winner will be obvious within days.
