I really liked Descend into Depravity for what it was, but I've never liked Nile, just because I don't respect Kolias as a drummer, frankly he hardly has any skill with anything but his feet.
And in my honest opinion, you're never going to get a technical death metal better than necrophagist. Muhammed is incredible, and Romain Goulon is one of the best drummers around. If you havent heard them, first off kill yourself, then when you've finished that, listen to this. http://www.youtube.com/watch?v=2SRD6...eature=related
