My vote for Debojit
-he has a full-bodied voice (as opposed to a kid-like voice, kids suck - seriously, i hate childrens' singing, so irritating)
-when he is singing his best, he sings with more depth and sensitivity, more attention to nuance
-his singing/voice is catchy - the lyrics stick to my brain for awhile afterward - for better or worse, he makes an impression
(i cannot say the same for vinit, whose voice is sure recognizable, but whatever he sings never really sticks with me afterward)
-he brings something new to every song he sings
-he has gotten this far without being the "favorite" - that says A LOT
-he can carry a slower tempo (e.g. parineeta song or shaan's "dil ne tumko" song) without putting you to sleep; this gives him a lot more versatility as a singer
-he does not need to wear a hat or talk about a mystery girl in his life to prove himself as a singer
-he has a good balance of confidence, ease, and humility (in his voice, in his performance, and his interactions)
-he is hard-working and challenges himself
-he acts with dignity
-he does not assume he is the best
-he does not complain when other contestants do well, he does not try to bail out when the going gets tough
other considerations:
-his wife ROCKS
-his mentor ROCKS
-his fans rock for bringing him this far
-his opponent sucks
-his opponent's mentor sucks the most
