Can't speak for copilot but Gemini cli is unbelievably bad compared to Gemini web.

CC has some magic secret sauce and I'm not sure what it is.

My company pays for both too, I keep coming back to Claude all-round

Agreed. I was an early adopter of Claude Code. And at work we only had Copilot. But the Copilit CLI isn't too bad now. you've got slash commands for Agents.MD and skills.md files now for controlling your context, and access to Sonnet & Opus 4.5.

Maybe Microsoft is just using it internally, to finish copying the rest of the features from Claude Code.

Much like the article states, I use Claude Code beyond just it's coding capabilities....

The Copilot IntelliJ integration on the other hand is atrocious: https://plugins.jetbrains.com/plugin/17718-github-copilot--y...

I'm amazed that a company that's supposedly one of the big AI stocks seemingly won't spare a single QA position for a major development tool. It really validates Claude's CLI-first approach.

It's sluggish in GitHub Codespaces, as it has so many animations.
