claude - org pays for it. org used to pay for both, and i preferred codex back then (~3mo ago).

i find claude to be significantly lazier or require significantly more guidance. it does, however, have better design and ui/ux intuition.

At work we only have access to claude / kiro. I only use it via cli since I find this to be the most flexible setup as claude can find stuff anywhere, read, write and run programs etc.

Mostly just Codex

Work I have access to both Claude Code and Codex. Use them both, typically on the same work. I like to do brainstorming and solution design with Codex GPT 5.5 High, and then have Claude Opus 4.7/4.8 high/medium do the implementation.

So far been quite productive for some greenfield rewrites and refactors of existing code. Though bug fixing our main project it's more hit and miss, though Codex GPT 5.5 High can be very good at spotting subtle issues.

I use my brain, pen and paper, because I work on serious projects that are of high risk and are mission critical. Not toy projects on GitHub.

Secondly, there will be a time where companies like Anthropic will disallow you from using AI in their interviews.

So you are cooked if you are over-reliant on coding agents.

I use Kilocode Vscode extension, still can't give up the IDE
