From what I read around I understand that node.js is good for simple projects, but not for heavyweights where concurrency and scalability is the key. This is where I'm pretty sure something like Typesafe stack (Scala/Play/Akka) blows it out of the water. Personally if I work on something I'd like to at least hope that it will be big someday, which is why I'm willing to spend some extra time, but choose the most solid platform that I can afford. Typesafe stack is the most impressive one at least for now, in my opinion.
