I don't think we are in a phase where we can confidently state that there's a correct answer on how to do development, productivity self reports are notoriously unreliable.
At least personally, the reason why I prefer CLI tools like Claude and Codex is precisely that they feel like yet another tool in my toolbox, more so than with AI integrated in the editor. As a matter of fact I dislike almost all AI integrations and Claude Code was when AI really "clicked" for me. I'd rather start a session on a fresh branch, work on something else while I wait for the task to be done, and then look at the diff with git difftool or IDE-integrated equivalent. I'd argue you have just as much control with this workflow!
A final note on the models: I'm a fan of Claude models, but I have to begrudgingly admit that gpt-5-codex high is very good. I wouldn't have subscribed just for the gpt-5 family, but Codex is worth it.
