Weird. It used to be the opposite. My own experience is that Claude’s behind-the-scenes support is a differentiator for supporting office work. It handles documents, spreadsheets and such much better than anyone else (presumably with server side scripts). Codex feels a bit smarter, but it inserts a lot of checkpoints to keep from running too long. Claude will run a plan to the end, but the token limits have become so small in the last couple months that the $20 pla basically only buys one significant task per day. The iOS app is what makes me keep the subscription.
Correct, this is the way. A year or two ago lots of people were saying to do the opposite, but at least now and probably also even then, this is better. Claude is a more sensible and holistic designer, planner, debater, and idea generator. Codex is better at actually correctly implementing any large codebase change in a single pass.
