• Localization (Chinese faces, culture)

Western Tools Excel At:

• Physics simulation (Sora's realism)
• Brand recognition (OpenAI trust)
• Enterprise ecosystem
• Research publication

For practitioners, the recommendation is clear:

• Today: Use Kling for production work
• Near-term: Evaluate Vidu when available
