In the thread “Ask HN: Do you use Claude Code, Codex, or something else?”
Helped: Brainstorming with Codex and implementation with Claude for rewrites.
Got in the way: Bug fixing main project is hit and miss.
… 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.
