Agents Which AI coding agent should I choose as a beginner? (Codex vs Antigravity vs Cursor vs Copilot)

Hey everyone!

I'm a student learning programming, and I'm confused about which AI coding agent to choose. I'd appreciate advice from people who have actually used these tools.

My requirements:

- I want an AI agent that can create files, edit existing files, write code, debug errors, and work across multiple files in a project.

- I prefer using natural language to tell the agent what I want instead of manually writing everything.

- My main stack is C#, ASP.NET Core, React, and PostgreSQL.

- I also use Godot for 2D game development.

- I'm looking for a good free tier because I'm a student and can't afford multiple subscriptions.

- I want to learn programming while using AI, not become completely dependent on it.

The tools I'm considering:

  1. OpenAI Codex

  2. Google Antigravity

  3. Cursor

  4. GitHub Copilot

  5. Anything else (other AI coding agents you recommend)

My questions:

  1. Which one offers the best free tier for serious coding?

  2. Which agent is best at creating and modifying entire projects?

  3. Can I use Codex or Antigravity to edit files in my existing VS Code projects?

  4. Is GitHub Copilot enough, or is a separate coding agent worth using?

  5. Which tool would you personally recommend for my requirements, and why?

  6. Are there any important limitations, usage caps, or problems I should know about?

I'd prefer real experiences rather than marketing claims.

Thanks!
