On the JVM space, for rapid prototyping this study[1] found the most adequate to be Vaadin, Grails and GWT. Personally, I prefer Play with Scala. I think it's fast enough for prototyping and can scale up beautifully both in application complexity and in load.
But, I believe the answer is that the "best" language/framework is the one you know better and are most proficient in.
