[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.
