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.
