90% of the time I extract people I am putting the smack to them with a strap and a snap...best method IMHO. Safer, faster, and easier on your truck.
The winch thing...remember they are for your truck more than others...use a strap!
why do you think a snatch is safer? Indeed faster and easier in most cases than winching, but the forces are probably inherently higher and harder to control for novices at it. I'd say more chances to damage something.
