Went with Option 3 - Too close to call; both runs are great!
As a HUGE fan of Neal Morse's work, both with SB and in his post-SB Solo works, they each have their ups and downs.
*IF* I had to choose, I would give the edge to Neal's solo career, but they're so different from each other, despite being SO much Neal, that they're both great in their own right.
Also, Neal has released some pretty awesome music since SB, songs like "The Creation", "The Door", "So Many Roads", "Seeds Of Gold", "King Jesus", "Reunion", "God's Theme", "Author Of Confusion", and so many more. He's also had some pretty sweet guest artists on his albums over the years, and I think he tries to keep all his albums from sounding too much like each other. It helps that nearly all of them have been concept albums, so they lend themselves to being listened as a whole rather than apart.
