My choices -
1. Sultan

2. Bajrangi Bhaijaan

3. Kick
.
Theatrically too it is the same. Sultan is the most watched followed Bajrangi Bhaijaan & Kick.
What an experience it was in theaters.
On tv as well as home media, somehow Sultan leads instantly. Till date haven't got tired of watching it. The film itself has that pull & it having Salman at his acting best is just icing on the cake.
Bajrangi Bhaijaan has the emotional connect.
Kick is sheer fun. Even when I watched it the last week, I could still connect to the fun Salmanisms.
Tiger Zinda Hai is like Hum Saath Saath Hain to me. Sony Max force feeds it the way ZEE does HSSH.
