I agree with Righty. Zero use in having both, though in my opinion there is an "x-factor" in favor of the Brutal. The backend transition in my opinion is better, it's a stronger, more powerful move, and it keeps the pins really low. Like Righty said, the Brutal is sharper off the spot, and actually hooks more overall, but on longer patterns I may go with the Defiant Soul, as it seems to roll earlier. In my opinion, the Soul's core is better and a bit stronger, but the Brutal's cover is one of the best in bowling right now. I drilled a Brutal last week, but the Soul is awfully good. Lol, just got me thinking, Brutal cover with a Soul core would be the best ball ever made.
