If it's because VSCode has built in IDE features like LSP integration, I personally really like Helix. Keyboard based (although not the same movements as Vim/Nvim, it didn't take me long to switch), and it's got built in LSP integration/stuff just works out of the box.

Although no LLM support in the editor, I personally just run Claude Code in a separate terminal, but if you want AI in the editor you'll have to look elsewhere.

I did try Neovim with Copilot a while back, and Google shows a few NeoVim Claude Code plugins, so it's probable that if you want an LLM in your text editor, NeoVim might work :)
