I am big fan. Its features are not immediately obvious, but it's a superpower to have. I'll mention just one - the ability to hit Ctl-Enter (MacOS) literally anywhere (in code editor, terminal, assistant pane) to get context-aware responses and code-diffs is super-useful.
I did try cursor but I'm just not into that whole VSCode feel (I am a JetBrains person, and zed lets you set the keymap to JetBrains-style, so most of my kb shortcuts still work in zed).
Zed is rust-based and extremely fast, and they are building it from the ground up instead of forking VScode like Cursor.
