Personally I like/love the gov-lock in the rear, if they are 14sf or larger. If you don't go crazy and know their limitations and function, they are more *versatile* (not better, every option is going to be better at one thing than another, it's just a seamless way to get traction, the downsides are what need figured out in your specific application) than anything else offered that doesn't have traction control.
That said, in the front, it would be horrible. I'd go with a truetrac in the front for a street/light off-road truck. Don't think I'd ever waste time with true limited slip in a full size truck used off-road unless the axle came that way. Better than open, but it's still going to slip under load.
