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?

They're all going to have quite divergent opinions on how to structure the fork and various other design decisions that would inevitably lead to forks of the fork again.

I think forking VS Code is probably the most sensible strategy and I think that will remain the case for many years. Really, I don't think it's changing until AI agents get so ridiculously good that you can vibe code an entire full-featured polished editor in one or a few sessions with an LLM. Then we'll be seeing lots of de novo editors.

The Claude Code extension on VS Code does very little (too little in my opinion). The integration level with agentic functionality provided by Antigravity goes much deeper in my 20 minutes or so of playing with it. The biggest value pieces I see is: Agent Manager window which provides a unified view of all my agents running across all my workspaces (!) where I can quickly approve or respond to followup questions and quickly brings me to the code in context for each agent, additionally, I can select a piece of code and comment on it inline and that comment gets sent to the correct, active agent. These two things alone are items which I have been looking for... Too bad I only have approval to use Claude Code at work. This looks promising.

I don't even know what the Claude Code extension does in vscode. I have it installed but hell if I know what it's doing. I run Claude in one of vscode's terminals, and do everything through there. I do see (sometimes) diffs pop up in the IDE, I guess that's the extent of this integration.
