Interestingly I disagree with all your points about VSCode.

It's fast, barebones by default, UI is minimal and it's Open Source enough that competitors forked from it.

I guess YMMV because there is a comment in this post from another user about Zed being sluggish.

I tried VSCode many times in my life and just hated the experience so much. It put me away from GUI editors for years, didn't want to try any of them. So ugly and so sluggish.

Zed was the first one that put me to rethink my position. It is so snappy on my Linux workstation and I don't have any issues with it's GUI. I finally switched from vim et.al.

But I know I have "weird" opinions, I also really dislike Apple products and their software.

Even not counting the LSP, for a text editor, it eats quite large amount of RAM.
