I’m currently using Claude Code Max 20× almost exclusively for software development. My workflow is heavily based on long autonomous /goal sessions, where Claude works on my project for hours. I’m considering switching to ChatGPT Pro with GPT-5.6 Sol/Codex , but before spending another $200/month I’d like to hear from people who have actually used both . A few questions: Which one produces better code overall? Which one is better for large repositories and long autonomous coding sessions? Has anyone switched from Claude Code to Codex (or vice versa)? Any regrets? Most importantly, which one gives you more usable coding time before you hit limits? Does ChatGPT Pro allow longer or more agent runs than Claude Max 20×? If you’re coding 8–12+ hours a day, which service feels less restrictive? I’m mainly interested in real-world experience , not benchmark scores or marketing claims. Thanks! 🙏 submitted by /u/GoalDistinct4449
