This probably isn't what you want to hear, but they're all good. When buying a bow, you buy features, ie, quieter, faster, smoother, longer, shorter, more durable, better service, better materials, less vibration, heavier, lighter, fat grip, skinny grip, etc.. Even color matters to some. The problem is, the desirability of these features varies with the individual. A lot will depend on what you're going to use it for, your physical stature, your personal preferences, how you'll get service, your ability to do your own service - even what your friends are shooting.

They'll all hit what you aim at if you do your part (assuming there are no manufacturing defects). Now, you have to decide what floats your boat.
