I haven't used the latter two. The Claude Code experience is very well translatable to Copilot and they are similar in features. There were not many examples of Github Copilot advanced usage like described in the article when Agent mode was just released (around 2 months ago?). But I was able to fully utilize it using Claude Code prompts and examples.
Copilot has a very direct advantage in my eyes - it has a plenty of models available: Sonnet 3.7, 4, GPT, Gemini, etc. That's something you won't get with the latter two.
