Better at planning, worse at execution. Ultimately, creates a working product.

Well this latest outage has me forming a position that a backup is mandatory. I've been using Codex for adversarial-review, so with this outage I'm now going to ensure the repo is tooled up to use both agents, and when an outage hits just switch over and keep going.

I think the only correct answer here is: It depends, on so many different things. Usage is definitely way more generous with codex and it isn't even close.
