If you listen to the songs only , and look at the contestants from vocal prowess and ability to emote ,
1.Sumedhas voice is good even on audio only , her sur control is okay but her ability to emote is excellent .I havent heard her sing any tragic songs yet so I cannot comment , but she has done justice to all her songs, sometimes better than the original
2.Poonam sings well, but has trouble in emoting naughty/love songs. she can sing tragic songs fairly well .her vocal command is excellent
3.Amanat's voice suits slow forlorn, semiclassical songs . His sur control is impeccable and his ability to emote tragedy is great . In fast numbers, he sang with sur , but he just didnt leave the impact as well as he did in slow numbers.
4.Raja is very good in KK/sukhwinder genre but out of his comfort zone, he has some major issues with voice modulation ,I think recently he has some strain on his voice ?? flu?/stress . .I like his voice quality which in unique
5.Aneek is an all rounder. he doesnot have any problems in slow/fast/sad or happy songs and he can emote very well. he can probably win the competition with his versatility .
The only thing i see is that he doesnot have a voice that would stand out and be different. such as Raja has a good high note voice, amanat for ghazals . We have quite a few artists already established in similiar voice. (sonu/shan/udit/etc)
