Feathers.js or standard node.js socket.io app?

Recently we started planing kind of chat app , which will be android and ios as well as web based chat app as well. But the things is really confusing me is technologies to work with. There are many frameworks around but which can be more reliable and good for future is a big confusion. Anybody can provide Suggestions would be great... thanks... btw for front end react is our choice to go with but backend is making a big confusion.

Thanks.. :)
