After seeing the performances today, I have to say these 2 deserve the top 2 spots. As someone stated earlier, II is about a complete package and if that is to be believed Amit and Emon proved today that they are not just good singers but great performers too. Prashant sang well but like Adnan said missed sur in some places and didn't put in the feel in the first song, though his second song was fantastic. Prashant can't perform as well and I felt the connection missing with the audience in the first song.
In totality, I believe Amit and Emon should be in the top 2 though it is obvious one will leave us tomorrow.
