well i have had all 3 mentioned above my hydraulic is the only 1 so far to be able to break 1 a new 11mm steel rope and it broke it easy as well (all be it that i was trying to move 3 or 4 cube of solid birt and clay

)
anyways it still broke the rope
pto driven winchs are mint apart from they work best with maneuls and that then involve a clutch

which dont like mud and crap in them)
if you can find a 60 auto then thats the answer for the clutch issue
leckys are good except that when youve killed the batteries after a few few hard hours winching they will then start giveing up as well ive had a 110amp alternater good flat out and it was still struggling to cope with thomos in the winter a couple of years back
all the above are horses for courses of course
all depends on how far and how hard you want to go and also how fast
the concept that leckys are good as you dont need the motor to run is fine , but only if the truck is on its side and you want to put it back onto its wheels if the motor is dead and you are in a bog there will generally not be enough amps in the batterys to get you out anyway.
so you will then still need the motor to be running this being the case go to a pto system either driving a winch direct or driving a hydralic
there you go my finger is now worn out
