The source lists Seedance as similar or better than Kling, cheaper by 20-35%, high-resolution capable, and stronger on natural motion.
Keep Kling when integration speed matters

Do not ignore the support caveat
The source notes fal.ai support for Seedance video may require waiting or direct Volcano Engine access. Budget fit is strong, but integration path still matters.
