I have a better experience with copilot myself, using it for a few years. I don't really let it generate algorithms or bits of data, it's mostly autocomplete, test setup, idiom generation. I find it helps me in the flow. But that's not an argument against your experience.
I have it turned off for text too, incidentally. Usually useless for Q&A as by the time I want to ask a question it's usually a hard one it fails on, though perhaps in some cases it helps me put me on a trail
