My purposeful caveat was 'software professionals', i.e. user in the loop engineering. Codex is much better at slinging slop that you later need to spend some time reviewing if you actually want to understand it.

This wasn't my experience at all.

I tried Codex for a short while but quickly went back to Claude. Found myself having to revert Codex changes all the time. Maybe I had subconsciously altered my workflow/prompting to work well with Claude, but somehow wasn't providing Codex with the correct context, not sure.
