§ The result
Bullhorn leads XOR on all 7 criteria.
Bullhorn finishes 24 points clear of XOR under rubric v1.0 — 54 against 30 — across the ATS-integrated and Screening cohorts. Bullhorn leads every one of the 7 criteria and 3 of them by 20 raw points or more, Article 11 Technical Documentation among them; XOR leads none. Article 11 Technical Documentation is the widest raw gap and the heaviest weighted swing at once (Bullhorn 62, XOR 20, 20% weight), but it accounts for only 35% of the weighted advantage Bullhorn holds across the 7 criteria on that side of the table.
Vendor profile
Bullhorn
Bullhorn is a cloud-based applicant tracking system and CRM for staffing and recruiting agencies, with AI features (Bullhorn Copilot/Amplify, automation, and Textkernel-powered search and match) that source, screen, and rank candidates against jobs.
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
Bullhorn is filed under ATS-integrated AI, XOR under Screening AI. They record no secondary category in common.
Both are in scope of EU AI Act, NYC LL 144, Colorado AI Act and Illinois HB 3773.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +23.8 — the difference between the two totals before either is rounded. Shares are of 23.8 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 +23.8.
§ Category-by-category
Raw score per criterion, with weighted delta.
Δ is Bullhorn 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.
