Hotstar has always been a better online tv app for me as I stay in the hostel away from home where tv is always missing. The channels of star brodcaster are availabe where I can watch the movies I want at any time in my laser time. As I found it more useful for watching daily show and these days I m hooked up watching ted talk india in hotstar. It provides me with all the source of entertainment like watching premier league and cricket live telecast.
It doesnot buffer much and streaming goes nicely for my network which I found one of the best featue of it.
so you are also fond of watching online tv and dont have time to watch on tv daily then it can be a better option for you. just go for it.
