Conclusion
All three AI assistants are excellent choices depending on your needs. Rather than picking "the best" one, consider:

- Match to your workflow - What does your typical task look like?
- Consider the cost - $20/month for unlimited if you need it
- Test the integrations - How well do they fit your tools?
My recommendation: Start with ChatGPT for breadth and community support, then add Claude if you do research-heavy work. Keep Gemini as a backup if you use Google Workspace extensively.
The future of AI work involves using multiple tools - each excels in different areas, so having all three in your toolkit is increasingly the norm rather than the exception.
