I'm just curious -- what specific issues have you had with Copilot?
I use it constantly (probably accepting a suggestion for every few seconds of typing), to the point where I'm starting to just not think about it anymore like I previously didn't think about normal autocomplete. It has written hundreds of perfect unit tests for me (perfect as in I have read the code and it matches virtually exactly what I would have written down to comments and variable names). That's so much mundane low-value typing that I just didn't have to do. Write the name of the test, hit tab, review, and move to the next.
It's certainly not perfect, and you must ALWAYS review what it suggests rather than blindly accepting, but it's incredibly valuable imo.
For reference, I use Copilot in both Rider and VS Code.
