## The short answer

Microsoft 365 Copilot leads six criteria — data use and training 7.0 to 3.2, integrations and knowledge 7.0 to 3.8, sovereignty 4.7 to 2.7, processing and models, admin and access and agent capabilities — and judges lean 6-0 on five, 5-0 with one tie on admin and access. Gemini for Google Workspace leads the seventh — pricing transparency, 5.5 to 2.0, 6-0 among judges — Starter, Standard and Plus are publicly priced at €6.80, €13.60 and €21.10 per user per month, while no captured page states a Copilot price. The genuine splits sit inside single columns: Copilot's sovereignty spans 4-6, the works council crediting the EU Data Boundary while the skeptic, head of IT and data protection officer cite Anthropic models outside it and the United States among storage locations; Gemini's widest spread, 4-6 on admin and access, turns on single sign-on, provisioning and audit logs, where the bench found no public information.

**Choose Gemini for Google Workspace if:**
- You need published prices for budget planning — Gemini for Google Workspace's Starter, Standard and Plus tiers are publicly priced at €6.80, €13.60 and €21.10 per user per month, and pricing transparency is the one criterion where judges lean its way, 6-0.
- Your finance team requires the annual-commitment discount stated up front — the captured pages state a 16% annual-commitment saving at regular rates.
- You need the offer's size limits visible before signing — the tier pages state a 300-user cap.
- Your security review starts from documented controls — the tier pages document data loss prevention, context-aware access, Vault, eDiscovery and tiered endpoint management, and admin and access is one of the two criteria where the bench scores Gemini for Google Workspace highest.

**Choose Microsoft 365 Copilot if:**
- You need written no-training commitments — data use and training scored 7.0 to 3.2, with documented commitments that prompts, responses and Graph-accessed data are not used to train foundation models, a downloadable data protection addendum, and ISO 27001 and ISO 42001 certifications.
- Your teams need grounded answers that cite their sources — integrations and knowledge scored 7.0 to 3.8, with a connectors API whose grounded answers store citations to their sources.
- Your works council or data protection review hinges on an EU residency commitment — the works council judge credited the EU Data Boundary in the Product Terms since March 2024, though sovereignty scores span 4-6 across the panel.
- You are deploying agents and want documented safeguards — agent capabilities scored 5.3 to 3.3, with jailbreak and prompt-injection classifiers documented; the captured pages give no public information on human approval before consequential actions.
- You buy through negotiated enterprise agreements, so an unpublished list price is not a blocker — the panel does not weight pricing transparency in Microsoft 365 Copilot's verdicts.
