> Mainly by having more things built-in. Kakoune is composable by design, relying on external tooling to manage splits and provide language server support. Helix instead chooses to integrate more. We also use tree-sitter for highlighting and code analysis.
I switched from Kakoune to Helix after using Kakoune for a few years. Helix, to me, is everything i loved about Kakoune but with better defaults. It being in a language i love also is fun, as i almost immediately forked it and changed a few things - handy when they're still figuring out plugins.
