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.
