These 2 balls have many differences.
As Rick stated, the Animal is going to want to get down the lane further, and will have a stronger breakpoint than the SF. If you have them at identical surfaces, the Animal will start of sooner (layout has to be taken into consideration there as well). Between the 2 of these, the difference I see most (other than the stronger breakpoint) is that the Animal hits much harder--giving more messenger pins.
