Different Goals, Not Just Different Quality
Wan 2.6 (Alibaba) and Seedance 2.0 (ByteDance) are both capable video models, but they're aimed at different jobs. Wan's signature is role-play (reference-to-video) — put yourself in the video using your own look and voice. Seedance is the all-round value leader with the strongest general quality.
What Each Does Best
Wan 2.6 — reference-to-video role-play (use a person's appearance and voice as references), multi-shot narrative, audio-visual sync, up to 15-second output, and strong character-identity retention across shots. The pick when the video needs to feature a specific person or character consistently.
Seedance 2.0 — tops the Artificial Analysis Video Arena for video with audio; native audio-video sync, an @ reference system (9 images / 3 clips / 3 audio), 8-language lip-sync, cinematic control, and best-in-class value (~$9/normalized minute). The general-purpose default.

Which Should You Use?
- Wan 2.6 → you (or a specific person/character) need to appear in the video with a consistent face and voice; personalized avatars; character-driven multi-shot storytelling.
- Seedance 2.0 → best overall quality and value for general production, ads, and social — the default unless you specifically need role-play.
- Need native 4K? Kling V3. Stylized/anime on a budget? Hailuo 2.3.
