I admit to knowing next to nothing about Rohit Roy (or Ronit for that matter, are they brothers, twins?). I just know that he looks as handsome as any model in this picture. Arbaaz doesn't fare so well in comparison, but he actually looks fine if you cover up Rohit with your hand. Those nice thick eyebrows - he's just missing his moustache. He really needs that moustache.
They look to me (as an American, I mean) like perfect archetypes for the main two types of Indians - Hindu on the left, Muslim on the right.
And the correct answer is easy: both!!
