Basically what @clivestaples already said. If you go to the Laravel Website [1] and look through "Ecosystem" in the navigation - that's what I am missing from Rails. And of course a more active community.

I'd say the Rails community has been a flat-line somewhat... but not diminished. Yes, it may not have been the hottest framework, but it's been rolling forward consistently and actively.

Not the OP but officially sanctioned tools and libraries are exactly what I envy from Laravel: auth, search, payments, hosting, etc.
