Kumar Sanu Vs Babul Supriyo? Better Vocal Quality ?

Although kumar sanu enrolled his name in one of the legend from 90's and was a bit overrated in 90's and at the same time babul supriyo couldnt able to sustain himself as one of the greatest ever playback singer ,,, but still who had better voice

Kumar Sanu by country miles. A superior singer with better voice. Babul was just a copy of Sanu. Nothing unique about him. This is why he faded soon as no one wanted a cheaper version of Sanu.

Sanu had a good voice but that's not the same as being a good singer. In my opinion, Babul Supriyo was better and didn't have a nasal voice like Sanu.
