Well I have Copilot Pro, but I was mainly talking about GitHub Copilot. I don't think having the Copilot Pro really affects Copilot performance.
I meanly use AI for programming, and (both for myself to program and inside building an AI-powered product) - So I don't really know what you intend to use AI for, but outside of the context of programming, I don't really know about their performance.
And I think Copilot Pro just gives you Copilot inside office right? And more image generations per day? I can't really say I've used that. For image generation I'm either using the OpenAI API again (DALL-E 3), or I'm using replicate (Mostly SDXL)
