User Meta Manager is a thin admin layer over wp_usermeta: it lists every meta_key written for every user, supports bulk delete and bulk add, and exposes the long-format key/value structure WordPress already maintains. The plugin is excellent at letting you see and clean raw usermeta and limited at telling you anything about the membership as a whole, because the surface is a row-per-key list rather than a member-per-row table.

SleekView reads wp_users joined with the meta_keys User Meta Manager exposes and pivots them into named columns at query time. Each member is one row. Role, account_status and any chosen meta_key (country, plan, referral_source) become real columns. Filter to a specific key value, sort by user_registered or by last_login and triage the membership without scanning a list of keys.

User Meta Manager keeps owning bulk-edit, bulk-delete and the raw key view. The table view owns the cohort surface, so the meta data User Meta Manager makes visible becomes something you can actually report on at the membership level.

User Meta Manager is honest about what it does: it surfaces the raw wp_usermeta key/value structure WordPress already maintains and lets admins bulk-edit and bulk-delete it. That is exactly the right tool for data hygiene and exactly the wrong tool for understanding the membership at the cohort level, because a list of keys never tells you who is in the membership or how they are distributed. SleekView pivots the same keys into named columns and renders each member as a single row, with role, registration date and any chosen meta_key sitting alongside email and last login.

Filters stack into a single query so the lapsed cohort, the Pro segment and the orphan-key audit become one-click saved views. User Meta Manager keeps owning the raw key view and bulk edits, while ops, marketing and managers get the per-member surface the dataset always deserved.
