It really depends.
These 2 balls give 2 totally different looks on the lane. The Animal reacts so much more in the backend. The Unleashed is much smoother----compared to the Animal.
If you were to put the same surface on both of these, the Animal is going to be MUCH stronger.
Let me put it this way-----I always throw dull equipment, and I have left the Animal's surface where it is because of how well it still rolls, hits, moves, hooks. My second one is on the way, and I am going to dull it down. I cannot imagine the overall HOOK that this ball will have with a dulled down surface.
I am a big Track fan. I loved both the Phenom and Phenom Unleashed, but they are setting the standards so high with the Animal.
More of a direct comparison since my Animal is drilled exactly like my Unleashed:
Length: About the same, but this is with the Animal with the factory finish.
Controll: The Unleashed is more controllable when the backends are fresh. I find the Animal easier to be used on more of a variety of conditions.
HIT: The Unleashed hits HARD, extrememly HARD. The Animal hits even HARDER. To this point, I thought the Mutant was the hardest hitting ball I have ever used, even harder than the Phenom or Unleashed, but the Animal hits even harder with more messengers than any other ball I have used.
HOOK: With each having the box surface, you will have to stand deeper with the Animal because of how strong it is in the backends. If the Animal was dulled down I imagine it will roll so soon that there would really be no contest.
OVERALL: Both balls are very good. If a bowler has slower ball speed they are probably better off with the Unleashed because the Animal is going to make them move much further left.
GOODLUCK!!!
