IMO the difference in the quantity and quality of packages available for React more than makes up for that difference.

I would say that Vue's core libraries are very well put together. Vuex, Vue-router, vue-resource, vue-axios, etc are all simple and easy to use. Personally, I wouldn't say either community has better supporting libs than the other.

Quantity: React has __hands down__ more packages and will have more packages than Vue for years to come.

Quality: I respectfully disagree. React does have quality packages, while Vue has official and high quality packages.

Moreover many of the react's package (eg: redux) can be used with Vue.

Well, being able to reuse other people's software (number of npm packages available for the library/framework) is an important variable when choosing a tool.
