On the basis that hydraulic winches are more powerful, reliable, durable and safer. The reasons for choosing electric rather than hydraulic are often based on cost and perceived complexity. After all a battery powered winch is just hooked up to the battery and away you go. If you don't expect too much in terms of reliability or performance this is roughly true, or absolutely true if the winch is just for show.
However, many people plan on using their winch for quite tough green-laning, or expeditions, where they need it to do some real work, or in winch competitions where the winch will really get hammered. It is these situations "just hooking it up to the battery" is a big mistake and wiring the system correctly starts to look a little more involved.
Shown below is a typical heavy duty battery-powered winch system, complicated isn't it? Lots of things to go wrong too, not too mention water ingress, earth problems, overheated wiring, etc. |

| Compare this with a hydraulic system and the complexity argument is instantly lost along with the cost differential. The H12 starts simple and stays simple, as the winch gets faster some things just get a bit bigger. Power starting at 4,5 tonnes, remains ample. |

| Catapillar, JCB and even the Pyramid builders used hydrailic power, not by accident, but by design. |
