Where Gemini fits
Gemini is often the practical choice when a task starts in Gmail, Docs, Sheets, Slides, Drive or Calendar. The advantage is convenience and context.
This matters most for teams that already standardize on Google accounts and policies.
Where ChatGPT still helps
ChatGPT is useful when you need a stronger draft, a clearer memo, a better strategy document or a second opinion on a Google-sourced summary.
A common workflow is to collect context in Google, then use ChatGPT to turn it into polished output.
Team controls
For company data, check Workspace settings, OpenAI settings and internal policy. The best AI is the one your team is actually allowed to use with the data in question.
