I haven't been able to get anything done with Codex. Claude Code is fast and "gets it". Also does better at running and testing its own stuff.
Its very odd because I was hoping they were very on par.

It also often fails to escalate a command, it'll even be like, oh well I'm in a sandbox so I guess I can't do this, and will just not do it and try to find a workaround instead of escalating permission to do the command.
ClaudeCode is used by me almost daily, and it continues to blow me away. I don't use Codex often because every time I have used it, the output is next to worthless and generally invalid. Even if it does get me what I eventually want, it will take much more prompting for me to get the functioning result. ClaudeCode on the other hand gets me good code from the initial prompt. I'm continually surprised at exactly how little prompting it requires. I have given it challenges with very vague prompts where it really exceeds my expectations.
For me, though, it's not remotely close. Codex has fucked up 95% of the 50-or-so tasks I asked it to do, while Claude Code fucks up only maybe 60%.
I'm big on asking LLMs to do the first major step of something, and then coming back later, and if it looks like it kinda sucks, just Ctrl-C and git revert that container/folder. And I also explicitly set up "here are the commands you need to run to self-check your work" every time. (Which Codex somewhat weirdly sometimes ignores with the explicit (false) claim that it skipped that step because it wasn't requested... hmm.)
So, those kinds of workflow preferences might be a factor, but I haven't seen Codex ever be good yet, and I regret the time I invested trying it too early.
