Verdict
An API-first, developer-configurable content platform with DAM features, built for enterprise teams (100+ users) with in-house developers, not a low-code tool for non-technical editors.
An enterprise DAM module within Adobe Experience Manager, for large organizations managing thousands to millions of brand assets across marketing channels.
A disk-native photo cataloguer and batch editor sold as a one-off perpetual licence, for photographers with large libraries who don't need Lightroom/Capture One-level RAW editing.
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.

Quoted per customer
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.
One-off perpetual licence; a cloud subscription is sold separately
Annual licence per edition, not per user

Most common complaint
No prices, and no explicit confirmation of on-premise on the product page
Not checked
The published prices are promotional and dated; list price is roughly double
It is a broader platform than a DAM — some capability has to be built rather than switched on
