Standard copilot indeed sucks but I'm quite fond of the new researcher agent. It spends much more time than any of the others I've tried, like Perplexity pro and openai.

From a one line question it made me a relevant document of 45 pages examining the issue from all different sides, many of which I hadn't even thought of. It spent 30 mins working. I've never seen Perplexity spend more than 5.

I won't't be surprised if they will significantly nerf it to save on computing costs. I think now they give it their all to build a customer base and then they nerf it.
