Copilot as a harness for the model is generic enough to work with every model. Claude sonnet, haiku, and opus are trained with and specifically for Claude code in mind.

Also, as a heavy user of both, there are small paper cuts that seriously add up with copilot. Things that are missing like sub agents. The options and requests for feedback that cc can give (interactive picker style instead of prompt based). Most annoyingly commands running in a new integrated vscode terminal instance and immediately mistakenly "finishing" even though execution has just begun.

It's just a better harness than copilot. You should give it a shot for a while and see how you like it! I'm not saying its the best for everybody. At the end of the day these issues turn into something like the old vi/emacs wars.

Not sponsored, just a heavy user of both. Claude code is not allowed at work, so we use copilot. I purchased cc for my side projects and pay for the $125/m plan for now.
