Neal Morse is indeed a great song-writer, even though he is quite formulaic. I don't really see that as a negative thing either, since he has this distinct style that you can hear it's him. That's highly admirable in a song-writer. You mentioned him being the 'king of melody', and I agree, for his melodies are what stand out most about his writing, to me at least. Add to that that he's a great keyboard player too. Even though too much of his music in a row gets tiring for me (because, quite frankly, a lot of it IS similar), I can definitely see why you would put him up this high.
