Codex + GPT-5-high is an offshore consultant. You give it the spec and it'll do the work and come back with something.
Claude is built like a pair programmer, it chats while it works and you can easily interrupt it without breaking the flow.
Codex is clearly more thorough, it's _excellent_ at picking apart Sonnet 4.5 code and finding the subtle gotchas it leaves behind when it just plows to a result.
And like you said, Claude is results first. It'll get where you want it to go, even if it has to mock the whole application to get the tests to pass. =)
