I switched from a GitHub Copilot subscription to Cody for VS Code, to give the competition a chance.

Cody's chat UI seems pretty good for making comparisons like this. You can set it to whichever LLM you want, including GPT-4o and Claude 3.5 Sonnet.

I haven't used Claude enough to do to a detailed comparison, but GPT4o and Claude 3.5 seem roughly similar for my coding questions.
