Verdict
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
A highly configurable DAM/MAM (Cortex) for museums, archives, media companies and multi-department organisations, with an admin ramp-up reviewers describe as weeks to months.
An enterprise headless CMS and composable DXP for developer-led teams needing multi-channel content delivery, with a native asset-management module that's newer and thinly reviewed.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.

No public price list; sales quote required for both packages (Prime and Ultimate). Adobe's own on-premise product description sheet lists separate license metrics per component — AEM Assets itself is licensed 'Per Instance', 'Users' are licensed 'Per User', Brand Portal is licensed 'Per Brand Portal User', and Dynamic Media/Personalized Media are licensed by 'Page Views per month' — so billing is multi-metric and only available via custom quote, not a single flat per-user or per-GB rate.

No published price on islandora.ca — the core software is free open source ("free to use and always will be"). Paid options are hosting/installation/migration/support/training contracts sold by independent third-party service providers listed on islandora.ca/service-providers (e.g. Born-Digital, discoverygarden); islandora.ca itself does not publish their rates or billing units.
