Generally you get what you pay for. Better strings, machined (not cast) riser, better limbs, bearings (not bushings), etc. The higher end bows are more pleasurable to shoot in some cases, also. Less recoil, less vibration, quieter. You may also find that as distance increases, so will accuracy differences. I've owned some of the less expensive bows, and they shot fine. I now shoot high end bows and find them more to my liking. And yes, my shooting has improved.
