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.

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

If you mean Codex is better at planning, I've heard the exact opposite. I'm told it's a beast if you tell it exactly what you need as it will execute it to the T whereas Claude will push back or do its own thing either because it thinks it's wrong or because it's feeling lazy

gpt-5.4 xhigh is a beast you only wanna unleash on your most complex tasks or spend 30 minutes watching the model reasoning how to do a git commit. For everything else i'd happily use a saner model like sonnet.

I use superpowers with both and have found the plan generation in codex to be a bit more thorough, so it's not the native planning mode necessarily

What about usage / quota?

Much better than Claude.

I've never hit the quota on Codex.

On Claude (Code), I used to hit it every other day before switching to Codex.

I hears they just shrunk the Plus tier quota. People on /r/codex have been complaining for a few days now.

They're trying to push people to their new $100 tier, which has a boosted quota for now.

I've started hitting Codex quota regularly for the first time the last couple of weeks, so I feel like they might be tightening the screws on the $20/month plan too. Someone paying for Max might have to work at it to hit the quota

After switching how is the code quality?

Much much better. Meanwhile you could exhaust Claude quota in 2 prompts, you can pretty much use Codex all day.

OpenAI sees an opportunity and is happy to set money on fire to have an edge over Anth. No issues

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.
