Just in case all of them are forks from VS Code... I'm pretty much sure you can port the extensions (eg, I used to use VS Code, then I moved to Cursor, then to Windsurf and now I went away and switched to Antigravity but the first 3 were able to install the same extensions)
Zed is not a fork of VS Code. It is one of the few genuine new editors in the last few years. Written in Rust and much smoother than VS Code and its forks.
