None of that matters if the model is worse. I say this as someone who uses both Claude Code and Codex all day every day — I agree with others in this thread that CC has much better UX and evolves faster, but I still use Codex more often because it's simply the better coder. Everything else is a distant second to model quality.
What kind of tasks are you having success with on codex? I’ve had the opposite experience. I’ll occasional compare solutions between the latest opus and codex with codex on x-high thinking. Sometimes I do get solution from codex that is impressive because it discovered an edge case that Claude missed.
I did notice that codex - like Claude - is now better about auto delegating to agents for keeping the context focused and agents in parallel.
