I know "try this other tool" is probably an eye-roll-worthy response, but as someone who's not a programmer but is in IT and has to write some scripts every once in a while and has a lot of AI-heavy dev friends - all I've ever heard about Copilot is that it's one of the worst.

I recently used Claude for a personal project and it was a fairly smooth process. Everyone I know who does a lot of programming with AI uses Claude mostly.
