It may come as a surprise to you, but I actually have 4 Neal Morse albums - Testimony, One, ? and the great Sola Scriptura (big Martin Luther fan, me) - and some five years ago I listened quite a lot to'm
Mystery I still have to get into - but will, no Mad promise
And I'm happy that you'r getting more into Opeth - super group, one of my real faves
So, on the metal front, guess it's: Opeth, the two DT's, Threshold, Haken, and Riverside, huh ? Got some other great metal groups waitin for ya, just check out my pantheon list .....
