Helix is awesome. But the plugin system is not there yet, so it is limited to its core features. There are no extensions so you only get a very good modal editor with very well made core features based on its LSP and Treesitter integration.

The only reason I don't want to make the switch is the missing (but WIP) support for multi LSP which is essential for frontend stuff (e.g. tailwind with React or just basic JSX support compared to VS Code). Snippets are WIP as well, but I could live with a workaround like pasting them from somewhere else.
