Completely agreed. Used claude and codex both on highest tier next to each other for a month. On complex tasks where Claude would get stuck and not be able to fix it at all, codex would fix the issue in one go. Codex is amazing.

I did found some slip ups in 5.2 where I did a refactor of a client header where I removed two header properties, but 5.2 forgot to remove those from the toArray method of the class. Was using 5.2 on medium (default).
