I will tell you from personal experience that the 12k lb hydro mile markers are pretty decent winches for the money. They pull great and the speed when in HI mode spools quickly to get the line in or out. Had one on a TJ that I loved.
Here is the downside. In stock form, they tie to your existing power steering pump (unless you run dedicated which is preferable). Not necessarily the output but when you call for winch hydraulics AND power steering, your steering takes priority. That means any steering input (which always happens when winching in a stuck position) causes the winch to slow or stop. I could not imagine a Cuck with hydroboost. My steering sucks whenever I am hard on the brakes. I could not imagine steering, holding the brake, and trying to pull cable all at once on the same pump. That brings the suck pretty quickly.
I would say for the money that is a great buy but you will get frustrated trying to run it unless you are just doing straight utility pulls and not in a recovery position trying to get up on a rock or a steep obstacle. You WILL want an aux hydraulic pump for that. Nice thing is they run cool non stop pulling hard.
You can run them in a disconnect situation, Mile Marker does sell hydraulic kits with quick connects for that situation although I would imagine that would become an oily mess after awhile.
