I've done evaluations of Github Copilot, Sourcegraph Cody and Gitlab Duo and Copilot is not garbage, but rather the by far leader among these other options.
Did you compare to Cursor? We gave up on Copilot a while back after Cursor blew us away. In the context of this article though, Cursor is very obviously tuned better towards Claude than OpenAI in my experience.
Cursor's agent is better, but the in-editor suggestions by Copilot when you're actually the one coding are very useful. Claude's agent is better than Cursor, so I'm not sure where Cursor fits in with this ecosystem.
