I think your knowledge is a bit outdated? Cursor definetley still has an edge, but VSCode Github Copilot UI has come a long way and using the same underlying models for both the results are fairly similar and change only in ux niceties
I tried copilot agent like 3 weeks ago. If that much has changed since then, props to Microsoft.
Zed is very nice, it’s just a totally different workflow. I think people who work in a domain where AI is not particularly strong would be better off with Zed, since Cursor’s way of reviewing edits is a little clumsy.
stuff like background agents cursor is way ahead.
Zed Editor is a nice contender too
