My opinion swings between hype to hate every day. Yesterday all suggestions / edits / answers were hallucinated garbage, and I was ready to remove the copilot plugin altogether. Today I was stuck at a really annoying problem for hours and hours. For shits and giggles I just gave Claude a stacktrace and a description and let it go ham. It produced an amazingly accurate thought train and found my issue, which was not what I was expecting at all.
I still don't see how it's useful for generating features and codebases, but as a rubber ducky it ain't half bad.
