I still use it as my main tool. I find it great for an existing code base because of the VS code integration by default. I can see how AI changes code I'm familiar. Plus, I think it's a great value. $10 for so much usage and access to Opus 4.6 and GPT 5.4.

It doesn’t do the same thing. Each has its own system prompts, tooling etc.

GitHub copilot sometimes doesn’t give you the model’s full context or something else.

The issue is also what does the model mean? Is Opus on Copilot the same as in Claude direct? There’s been lots of hosting providers trying to save money and cut corners. Some employ compression techniques.
