Verdict
A quote-only enterprise DAM (formerly Widen) built on configurable metadata and external sharing portals, for organisations already standardised on the Acquia stack.
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
An open-source PHP/Symfony platform unifying PIM, DAM, CMS and MDM on one codebase, for teams with in-house developers or an integrator partner rather than a marketing team wanting to self-serve.
An open-licence, self-hosted DAM for teams with in-house server admin capability, trading a free licence for the time to run upgrades, tune dependencies and troubleshoot it themselves.

Organisation size, user count, storage volume and feature set
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.
Annual licence per edition, not per user
Self-hosted: no licence fee. Hosted: a user ceiling per tier

Most common complaint
Cost depends on four variables at once, none of them priced publicly
Not checked
It is a broader platform than a DAM — some capability has to be built rather than switched on
The free route is genuinely free of licence fees but moves hosting, upgrades and support onto you
