I'm pretty sure Anthropic is the only company that actually dogfoods their CLI tool.

Gemini seems like an afterthought an intern did, Codex has cool features but none of them align with real-world need.

I actually defended Gemini CLI when someone said this a few days ago. Then Murphy's law hit me with bug after bug, all of which have been reported many times already going back over year or more. I keep having to totally clear out the ~/.gemini folder and then it works again for a while.
