It depends on what you're building. E.g. for GUI-heavy apps and fast development, I favor JavaScript (or any other flavor like Coffee/Clojure/TypeScript) + React. For execution speed and simple (or no) interface I'd choose Go, or if I could handle some platform instability I guess I would go for Rust (I still love C, but it feels like a dead weight for modern development).
