## The short answer

The benches lean differently by criterion, and that difference is the answer. Contentstack leads one criterion, collaboration and approval — 7.0 to Storyblok's 6.5, three judges leaning Contentstack, none Storyblok, three ties. Storyblok's clearest is distribution and integrations — 7.3 to 6.0, six judges leaning its way, no ties — plus pricing transparency, five leans and one tie at 7.2 to 6.3. Content model and reuse draws five ties at means 6.0 to 6.2; AI and content rights draws four at 4.0 to 4.3. Sovereignty splits two judges each way and two ties at 4.2 to 4.3; the captured attributes show unknown ownership and data residency for both, legal entity jurisdiction AT for Storyblok but unknown for Contentstack, whose subprocessor exposure reads US CLOUD Act. Editorial planning is each side's lowest mean, 2.0 to 3.0. Weighted totals favor Storyblok for four judges; the content lead and data protection officer tie.

**Choose Contentstack if:**
- You need approval rules with a two-distinct-reviewer minimum against self-advancement — collaboration and approval is the one criterion where the table has Contentstack ahead, 7.0 to 6.5, three judges leaning its way and none Storyblok's.
- Your process requires named workflow stages plus an audit log recording each stage transition, both cited in Contentstack's collaboration and approval verdict.
- Your editors must not be able to advance their own content past review; the two-reviewer minimum documented in Contentstack's collaboration findings covers that case.
- You operate in fallback locales and multi-locale queries — content model and reuse sits at a mean of 6.0 with five judges tying, and Contentstack's verdict cites those capabilities.

**Choose Storyblok if:**
- You build delivery around a GraphQL API with webhooks, an app directory and a public status page — distribution and integrations leans Storyblok six judges to zero with no ties, 7.3 to 6.0.
- You must see published prices before talking to sales — pricing transparency leans Storyblok five judges to one tie, 7.2 to 6.3, with Growth at 99,00 €/mo including 5 seats, Growth Plus at 349,00 €/mo including 15 seats, published per-unit overages, and a free Starter plan requiring no credit card.
- You schedule individual stories with workflow statuses — editorial planning leans Storyblok three judges to zero with three ties, mean 3.0 to Contentstack's 2.0.
- Your procurement requires an operator whose legal entity jurisdiction is recorded as AT — the captured attributes list AT for Storyblok, and unknown for Contentstack, whose subprocessor exposure is recorded as the US CLOUD Act.
- You want named AI models in the product — two judges lean Storyblok on AI and content rights, 4.3 to 4.0, and its verdict names the models.
