§ The result
Plum leads XOR on all 7 criteria.
Plum finishes 24 points clear of XOR under rubric v1.0 — 54 against 30 — across the Assessment and Screening cohorts. Plum leads every one of the 7 criteria, XOR none of them, and the closest of the 7 is FRIA Support, Plum 28 to XOR 25. Bias Audit Transparency is both the widest raw gap and the heaviest weighted swing — Plum 83, XOR 18 — and at an 18% weight it carries 48% of the weighted advantage Plum holds across the 7 criteria on that side of the table.
Vendor profile
Plum
Plum is a pre-employment talent assessment platform that uses a Five-Factor (Big Five) psychometric Discovery Survey and a Talent Match model to score and rank candidates on behavioral "durable skills" for role fit, hiring, and development.
Vendor profile
XOR
XOR is a text-first conversational-AI recruiting platform that pre-screens and scores high-volume and hourly candidates with recruiter-defined knockout/scoring questions over SMS, WhatsApp, and Messenger, then auto-schedules interviews on the recruiter's calendar.
§ The record
Plum is filed under Assessment AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of NYC LL 144, Illinois HB 3773, EU AI Act and Colorado AI Act. Only Plum is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +24.6 — the difference between the two totals before either is rounded. Shares are of 24.6 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +24 beside that +24.6.

Raw score per criterion, with weighted delta.
Δ is Plum minus XOR.

§ Evidence
Cited sources and documented absences, criterion by criterion.
An absence is a finding, not a blank: the reviewer looked for a named artefact and recorded that it is not located. Where a source sits is a fact about hosting only.
