Well the way is see it is the lift would be better in the long run. i have an 82 fj40 right which is my daily driver that is lifted and has a winch. i've used the winch maybe twice, once to pull a truck out of a ditch and the other to pull myself out of a creek but then again i was wheeling by...
When considering price and how much it will help you which would be a better investment of the two for an 80 with lockers, a winch or a 2 inch lift, lift will cost 700 i guess or sor has it for 550 or a winch which is i guess 1000 plus a bumper for 500.
So:
lift at 550
or
bumper and winch at 1500
