A few impressions for fellow Claude Code users who are considering dipping their toes in the water: Usage limits : GPT-5.5 high effort feels 2-4x better than using Claude Code Sonnet 4.5 medium effort. I was able to downgrade from two Claude Max 20x accounts to a single $100 ChatGPT account. UI : Codex takes getting used to, but honestly 2-3 days later it no longer feels worse than Claude Code. Quality : GPT-5.5 high feels like it’s outputting much better quality code than Opus 4.7 Transparency : It is much easier to view the agent’s verbose output using Codex than Claude Code. Company : Anthropic is a much more toxic company than OpenAI. The latter’s CLI is open-source, regularly offers extra usage and has reset usage limits multiple times over the past couple of months. Uptime : Codex has not gone down once during my usage. Claude Code has had an outage every 2-3 days during that same time. Biggest downside: Claude Code has a more mature plugin system and skills support more frontmatter properties than Codex does. This is more likely to impact plugin developers, such as myself, than end-users. Ask me any questions you might have. submitted by /u/cowwoc
