In my opinion Hike is more powerful and have better features than Whats-app. And also it is an Indian app so we should promote Hike rather than Whats-app. In Hike we can easily change chat interface according to our friends. Like if I am chatting with my best friend than I cann change my chat interface to Friends-forever interface. And it has several exiciting stickers like Bollywood stickers,Indian Stickers,etc,. Moreover in comparison with Hike Whats-app never provide any features similar to Whats-app . And in Whats-app we are restricted to send files sizes upto 16mb but in Hike we can send upto 100mb. So in comparing both social app I personally recommend Hike as a better social app.
