§ The result
Ribbon leads XOR on all 7 criteria.
Ribbon sits 13 points above XOR under rubric v1.0, 43 against 30, with both filed under Screening. Ribbon leads every one of the 7 criteria, XOR none of them, and the closest of the 7 is Post-Market Monitoring, Ribbon 37 to XOR 33. The advantage Ribbon holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Ribbon 42, XOR 20, 20% weight), yet it supplies only 33% of the weighted points Ribbon gains across the 7 criteria it leads.
Vendor profile
Ribbon
Ribbon is an AI recruiter that runs voice and video screening interviews with applicants around the clock, scores each interview against default and custom rubrics, ranks candidates for recruiter review, and syncs the results to 60+ applicant tracking systems.
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
Ribbon and XOR are both filed under Screening AI. They record no secondary category in common.
Both are in scope of EU AI Act, NYC LL 144, Illinois HB 3773 and Colorado AI Act. Only Ribbon is in scope of Mobley v. Workday.

Weighted delta is the raw difference times the criterion weight, so the 7 figures above sum to +13.5 — the difference between the two totals before either is rounded. Shares are of 13.5 points of movement counted without direction. The table below rounds each side to a whole number first, so its Δ raw total reads +13 beside that +13.5.
§ Category-by-category
Raw score per criterion, with weighted delta.
Δ is Ribbon 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.

Ribbon has 35 evidence rows across 7 of 7 criteria — 31 with a source URL, 4 documented absences; XOR has 18 evidence rows across 7 of 7 criteria — 11 with a source URL, 7 documented absences; some documentation or audit rows for Ribbon sit on a domain separate from the vendor's own site.
Provenance
The scores above are documented by 53 evidence rows on file for these two vendors: 35 for Ribbon, across 2 distinct source domains, and 18 for XOR, across 1 distinct source domain.
