Why are so many still using CC and not Codex
If you are using literally any of Claude Code’s features the experience isn’t close, and regardless of model preference (Claude is my least favorite model by far) you should probably use Claude code. It’s just a much more extensible product for teams.
Losing access to GPT 5 Pro is also a big hit… it is by far the best for reading full files/repos and creating plans (though it also by far has the worst out of the box tooling)
Codex writes higher quality code, but is slower and less feature rich. I imagine this will change within months. The jury is still out. Exciting times!
Maybe CC users haven’t figured out how to parallelize their work because it’s fast enough to just wait or be distracted, and so the Codex waiting seems unbearable.
