While I might be slightly biased because I don't really listen to much Neal Morse, I think in terms of pure vocal-ability, Duda is a better man. Now, maybe you prefer Morse's voice or maybe you like his music more. I can totally see why someone might prefer him, but in terms of range/vocal-ability I still think Duda is a clear winner. (I've heard maybe a handful of Morse songs and one album)
