What exactly are the "extras" that Copilot gets?

I've had a Github Copilot subscription from work for 1yr+ and switch between the official Copilot and Roo/Kilo Code from time to time. The official Copilot extension has improved a lot in the last 3-6 months but I can't recall ever seeing Copilot do something that Roo/Kilo can't do, or am I missing something obvious?
