Among the male singers, I think Harshit has the better voice and range by far. Ishmeet has such a nice soft voice that he will be able to sing the romantic numbers very well. Even without the classical base, I have not heard Ishmeet go off sur. Once Ishmeet gets classical training he will have a even better range.
Abhaas is suberp too but he should be guided on the song selections. Sometimes I feel that he does not pick the songs that showcase his voice.
Harshit and Abhaas should be the final two.
