Verbatim evidence the judge attached to positive labels.
“Best headless option for marketing teams because it includes a visual, real-time editor” Gemini 3.1 Pro · Marketing CMS · scale prompt · first choice
“## Recommendation: Storyblok” GPT-5.6 Sol · Marketing CMS · paraphrase prompt · first choice
“Storyblok's visual block editor is genuinely strong for marketing teams — which usually makes it the better headless pick for a *marketing* site” Claude Opus 5 · Marketing CMS · direct prompt · alternative
“You need a custom frontend or content shared across multiple sites/channels, but still want visual editing for marketers.” GPT-6 Astra · Marketing CMS · direct prompt · alternative
Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.
“Contentful, Sanity, Storyblok, Strapi and similar systems can be excellent. But “headless” is not automatically more modern or better.” GPT-5.6 Sol · Marketing CMS · negative prompt · soft negative
“the trap here is that a marketing site is not the use case headless was built for” Claude Opus 5 · Marketing CMS · paraphrase prompt · soft negative
Claiming is free and changes nothing in the data. A claimed page gets a verified contact who is told when each edition publishes; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Storyblok, applied by version and listed in the change log; and a logo and one-line description supplied by the vendor and marked as such.
It does not get any change to labels, shares or quadrants, any preview, or any say over which quotes appear. Sponsorship is separate: a sponsor funds categories or buyer dimensions and is named on what it funded, and the rules are the same for every sponsor.
