No, they're not all the same. That's like saying an Edsel and a Mustang are the same because Ford made both. Like any product, depends on what is spec-ed to the factory. Warn seems to not take a drubbing for their imported winches. And not all imports have the same bad rep that is implied here. Most reports on the Badlands 12k are actually pretty positive once the discussion gets beyond the Warn fanboys point.
Most important is doing a good install, knowing your winch, and knowing how to safely recover stuff with it. Mostly you don't hear specifics of why a winch failed, just that it did. It is so easy to mess up any winch with a little ignorance about duty cycle. Yeah, some resist the "loose nut behind the wheel" problem better than others, but none are immune to that. If you regularly abuse your equipment, yeah, you should spend top dollar, because you're going to need all the help you can get if you don't know better, but it won't make the winch immune to abuse.
