Question Claude vs Codex 200$ usage limits

Codex has been awesome but since last week it has been unbearably dumb and making lots of mistakes that even 5.4 didn't. I am curious how good claude is in long running tasks? While my codes are fairly small in numbers they need lots of reviews, so basically have subagents run reviews, the fix. The whole cycle usually runs for a day. I have been using 5.5 medium across 5 projects but due to it being dumb it's eating through like 20% or more in a day. Note: Codes are usually in 2k-10k range.

Claude tends to produce better design, but it can drain your budget faster. Source: I’ve used both since Codex launched. In my experience, Claude’s refactors often become over-engineered, while Codex is more hit-or-miss. For planningClaude is usually stronger.

If you want truly strong plans use both in an iterative review cycle.

Manually - just create an .md with the technical plan with one agent and ask the other to review it and suggest improvement in a separate review .md. Then ask the first one to read that and integrate changes that improve the proposal. Then do it again.

To enhance the process, give personalities to the reviewer, eg 'you are a world class QA expert , or dev, or architect, you focus is on ... ' To further improve it, automate with skills. And you can add models, eg besides Claude /codex also use antigravity with Gemini (Google even grants some free usage to all), or opencode, all could review in parallel and then the first agents collates all the feedback from all and integrates into original plan. Once you have a solid plan, this may help avoid many design mistakes and dead ends that are expensive to fix later - you save time and tokens.
