How does the NES functionality compare to the one implemented by folke/sidekick.nvim?

[icristianhernandez]

Hey, good day! I have been seeing news about NES implementations in Neovim for about three months now, haven't I? The way the developers talk always makes it seem like some part of the implementation isn't finished yet. Around the same time, that feature comes to copilot.lua, and folke releases a new AI plugin with NES.

So, my questions are:

• Is the technical implementation different?
• Which one has better performance?
• Which one offers better suggestions?
• Are they in development or their core functionality are already well implemented?

Thanks for the help in advance!
