In terms of voltage, a Taser is generally stronger than a cattle prod. Tasers typically deliver a shock of around 50,000 volts, whereas cattle prods usually deliver around 4,000 to 5,000 volts. However, the effects of a cattle prod or Taser will depend on various factors such as the duration and intensity of the shock, the individual's health and medical history, and the location on the body where the shock is delivered. It is important to note that both devices can cause pain, injury, and even death if misused.
