Well for me it's the style I prefer to use (Leopard style) and the techniques that come with it. Double leopard thrusting punch, leopard pawing at the butterfly, back fist punhing at the meteor, upward thrusting leopard punch, lying leopard stretch. All of these forms use low/mid kicks, elbows, knees, leopard paw, leopard punch, leopard fist, leopard claws. A very fast style with multiple hits, kicks, punches, rakes to the face, side of the head and eyes. I'm 6'. 150 lbs, so this style works good for me where I have the speed and flexibility for fast attacks.
