Bottom Line: Sora leads in pure video quality, but Kling remains the most practical choice for China users. AI video has evolved from toy to production tool.

Individual Analysis
Sora - Quality Benchmark
Best physics simulation and scene consistency. Movement and lighting look remarkably natural. Requires ChatGPT Plus/Pro, no China access, and gradual rollout.
Kling - Best for China
1080p output, excellent Chinese prompts, free daily quota. Sufficient for short video creation.
Runway - Professional Choice
Richer editing features than Sora: video modification, style transfer, motion tracking. Better for complete editing workflows.
