There is no "best" tool, only the tool best suited for the scenario. Use the following table for a quick self-test:

🚀 Selection Matrix

Your Needs Recommended Tool Reason
Maximum Security & Compliance Claude Code Powerful Hook system can enforce Lint/Test review.
Open Source Fan, Want Deep Customization Gemini CLI The only open-source option; fork the source and customize.
Multi-model usage, Avoid Vendor Lock-in Antigravity Native support for one-click switching between Gemini/Claude/GPT.
Heavy Frontend/UI Development & Debugging Antigravity Built-in visual browser Agent provides an unbeatable debugging experience.
Need CI/CD Automated Batch Processing Gemini CLI / Claude Code Excellent CLI support (-p mode), ideal for unattended tasks.
Budget-Sensitive, Small Personal Projects Gemini CLI Most generous free tier; flexible billing via Vertex AI.
Enterprise-level Complex Workflow Orchestration Claude Code Mature Plugin/Skill ecosystem; controlled and rigorous processes.
Unfamiliar with Terminal, Prefer GUI Interaction Antigravity Experience closest to a traditional IDE with a gentle learning curve.

Summary: The One-Liner Guide

  • Use Claude Code if you are a hardcore developer seeking "programmable, controlled" power.
  • Use Gemini CLI if you need flexibility, open-source transparency, or are building a customized Agent tool for an enterprise.
  • Use Antigravity if you want the strongest visual presentation, cross-model capabilities, and ultimate UI development efficiency.

Since the configurations for these three tools (.claude/, .gemini/, .agents/) do not conflict, you can even install all of them in the same project and let them "each show their strengths" for different tasks.
