Codex has been better for me, but it's WAY too nitpicky/defensive. It always wants to make changes that add complexity and code to solve a problem that's impossible to happen (e.g. a multiprocess race condition on a daemon I only ever run one instance of).

You just convinced me to try it. Claude just copy pastes, does search and replace, zero abstractions and I'm the one that needs to think about the edge cases.

Same here; that’s very annoying because it adds a lot of entropy to the code, and people don’t always take the time to clean things up.
