Verdict
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
A modular, metadata-heavy DAM aimed at large organisations with IT capacity to manage taxonomy, sold through quote-based pricing with on-prem and private-cloud options.
An open-source, community-governed digital repository platform on Drupal, for libraries, archives, and museums to manage digital collections.
A self-hosted file-sync and collaboration platform some organisations stretch into asset-library duty; tagging, batch metadata editing and dynamic tag-based collections are still limited or missing.

Billed on
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.
A modular model — you pay for the modules you take
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.
Subscription per user per year, cheaper at volume

Most common complaint

The pricing page works as a lead form rather than a price list
Not checked
It is a file platform with DAM features rather than a DAM: asset-level metadata and rights are thinner
