❓Is Codex Better and Faster Than Claude Code on Subscription for Vibe Coding?

Hi everyone,

For those who have used both Claude Code and Codex through their subscription plans, is Codex actually better and faster for vibe coding?

I have been using Claude Code on a subscription for a while. It is often very capable, but I have found it extremely slow. I switched from the Mac desktop app to VS Code, hoping it would improve the experience, but many tasks still take a very long time.

Lately, I have also noticed more mistakes and patches that frequently break things. I am now spending more time debugging and repairing its changes than making progress on my projects. I have tried several Claude models, including Fable 5, Opus 5, Opus 4.8, and now Fable 5.1.

I have heard that Codex is faster and more efficient, but I would appreciate clarification from people who have used both:

1. Can Codex be used through a subscription, such as the $200 ChatGPT plan, with coding limits comparable to Claude Code? Or does extensive use require separate API billing?

2. Is Codex genuinely faster and more reliable than Claude Code for vibe coding?

3. Can Codex take over projects that were started in Claude Code by reading the existing codebase, `CLAUDE.md`, and other Claude project files?

I would especially appreciate feedback from anyone who has used both platforms extensively on real projects.

Thank you so much for your help.🙏
