How long ago was that? 6 months ago I switched from VS Code to Cursor, which at the time was FAR superior to Copilot. Around a month ago I switched back to VS Code, and found there's not much difference any more. Autocomplete in VS Code is still less good, but the agent mode in VS Code feels pretty similar to Cursor's (albeit a little slower, perhaps).
To be honest I think both are quite limited by context length (in that they try to limit the context they send to the LLM and hence cost), and so I find myself using Gemini 2.5 in AI studio with the 1m context length, and asking it to generate instructions for Copilot (which seems to work pretty well)
