Right now what the music industry needs is a versatile singer not a copycat. Vineet is a good singer, but why should we vote for him? We have Sonu Nigam who is rocking the music industry, so why do we need someone who copies Sonu. Till now Vineet has not sung anything that is very difficult to perform. If someday he sings a song like "Madhuban me radhika nache re" by Rafi saab then we will agree that he is an excellent singer.
One the other hand Debojit has been extremely versatile. If he has slipped a few times because he tried to sing all the difficult songs that no other contestants will even have the guts to try. Just look at the range of songs he has tried: 1) Ae Subah Tu Shabnami, 2) Main Hoon Jhumroo, 3) Badi Sooni Sooni Hai, 4) Humma Humma, 5) Ek Chatur Naar, 6) Ek main hoon (Fida) and etc. What a range of songs đ đ. He is the most classically trained singer too. He has a very original, melodious, and wonderful voice, which is perfect for playback. So please vote for Debu. He is genuinely good or else ID wouldn't have appreciated him so much. ID does not have any double standard like the other mentors and he has always given his honest opinion even if it is from his own gharana (remember how he scolded Twinkle). He is the same person who praised other contestants too.
Just my personal opinion. Sorry if I have offended anyone.
