[Question] How to choose between Copilot SDK and Agent Framework?

As a beginner, I have tried to do same project by these two ways - **Github Copilot SDK** and **Microsoft Agent Framework** to learn these. I noticed some differences in atomicity, particularly regarding events. But I feel like there's something that hasn't been discovered yet.

So, could you experts share your thoughts? This can help others choose the right product and deepen their understandings.

The issue names GitHub Copilot SDK and Microsoft Agent Framework but does not identify files, tests, or an entry point. First clarify the comparison criteria and locate the relevant documentation or examples; the work would be complete when the differences and product-selection guidance are documented for beginners.
