I never used Claude, but that's basically my sentiment about copilot when compared to Gemini.
Then I forbid all this BS in agents file. Gemini follows it. Copilot ignores it with all its strength. Then I tell it to stop trying on the chat prompt. 2 minutes later it does it again.
Not just at prompt engineering level, but at all levels, Gemini guardrails are better ( well it was, they killed it and replaced with anti gravity now).
