I know this is tongue and cheek but if anyone out there really feels this, there's two good directions to go: 1) Choose _any_ of your candidate frameworks and gogogo. 2) Choose something like golang and learn to bring-your-own-framework. Either way you'll come out _far_ ahead of where you'd be if you'd spent your time just evaluating.

Now I'm going to write a web framework in Go called "gogogo" just to really confuse future readers of your reply.

I would recommend Elixir on the backend and Elm on the front. Or better yet, fishing.
