After spending weeks building a full-stack project with Claude Code Opus4.6 , Codex GPT 5.3 , and Copilot Auto Mode , the biggest difference isn’t benchmarks or code quality, it’s that Claude Code actually runs continuously until the task is done. Copilot agent and Codex will do a small chunk, then stop and ask “should I continue?” or “shall I proceed with the next step?” You end up babysitting the AI through every subtask. Claude Code just… keeps going. You give it a complex task (refactor this system, add this feature across 15 files, fix this bug and run tests), and it works through the whole thing autonomously — reading files, making changes, running builds, fixing errors, iterating. No hand-holding. For context I just built a OSS lib https://github.com/GLINCKER/geokit where Claude handled multi-file changes, SSE streaming, SQLite persistence, and UI components in continuous sessions. Anyone else notice this? It’s not in any benchmark but it’s the #1 reason I stick with Claude Code. submitted by /u/Familiar-Classroom47
