Pros & Cons
Gemini Enterprise
Pros
- Permission-aware search across connected company apps, with grounding in Google Search and the web
- Strong security controls on the higher editions: CMEK, VPC Service Controls, US or EU data residency, Access Transparency and Cloud Audit Logs
- Google states that enterprise prompts and data are not used to train its foundation models
- Standard and Plus scale without seat caps and include an Agent Marketplace and a no-code agent builder
- Tight fit with Google Workspace, which G2 reviewers praised
Cons
- Business edition has only selected connectors and no agent builder or marketplace
- Several prices, including Plus and Frontline, are not published by Google
- Usage beyond quotas, partner models and developer tools are billed separately, so costs are hard to predict
- Memory is per user, and Google's docs say source changes can take up to 24 hours to take effect
- G2 has only a small number of reviews, and one reviewer said memory seemed shorter after an update
Microsoft 365 Copilot
Pros
- Works directly inside Word, Excel, PowerPoint, Outlook and Teams, so users don't need to switch to a separate tool.
- Grounds answers in the organization's own email, SharePoint and OneDrive data, and respects the tenant's existing security and compliance settings.
- Teams meeting summaries with action items save time for meeting-heavy teams.
- Copilot Business brought the price for organizations with up to 300 users down to $21 from $30 while keeping the same functionality.
Cons
- It is an add-on, so the per-user cost comes on top of the base Microsoft 365 license.
- Reviewers report inconsistent output quality across the Office apps.
- Some users report daily usage or message limits.
- Overlapping product names (Copilot, Copilot Pro, Copilot Business) have led buyers to purchase the wrong tier.
