Pick Gemini if…
- You need real autonomous-agent capability (plan + execute multi-step tasks), not just chat.
- You want the cheaper option (starts at $19.99/mo, Grok starts at $30/mo).
- You specifically need Gemini 2.0 models or Workspace integration, which Grok doesn't ship.
- Your primary use case is Workspace tasks or Research — Grok doesn't list this.
