I used Zed for a few months a while ago. It feels quite fast, good extension availability even for how new it was, and offered a comparable experience to VSCode, but without the bloat. Sadly it quickly started going down the AI editor/LLM infested route and most development went into that, meaning actual fixes and improvements were getting slower (part of my reason for leaving it). It also introduced a few unwelcome changes to their ToS, starting the forks you see today. But overall it was a pretty nice editor, it gets out of the way and lets you focus on work instead of tinkering.

Had to stop using it due to an intense graphical flickering when running on Sway that took way too long to fix, so I switched back to neovim while waiting for a fix and just stayed there.

I used to use Atom back when , it was ok. Zed / Gram just feels more lightweight and performant , yet having everything you need without any customisation ( I never tried ai or collaboration features in Zed) - nothing live changing, just a good editor for rust . Anyway, I switched to helix and after some configuration it provides much better experience.
