Well, I am interested in Om Shanti Om only because of the title song featuring 30 filmstars. And Saawariya being one of the first ventures by Hollywood Studios in Indian cinema.

I think OM Shanti Om is an all out entertainment full of masala, where as Saawariya is  another one of  Sanjay Leela Bhansali's trademark tearjerkers. Given a choice I will go to see Om Shanti Om because I seek entertainment in Indian cinema.
