Posi=locked all the time=bad for on road performance
selectable locker=can lock and unlock at you discretion
LSD=allows limited slipping on tire speed
For my money I would go with the air or e locker since they are selectable (expensive, yes).
I would say that most people can actually get away with a LSD, but you only said you would be beating the ***** out of it off road. there is a lot of off road out there. The terrain makes a difference also, what are you going to be running on???

Actually, POSI-traction is just general motors term for limited slip, much like Ford calls them trac-lock. To answer you question, the stock limited slip is mediocre at best, when they're new. But as they wear (and they wear quickly), they revert back to open differentials. They'll help with some situations, but overall, not much better than open diffs.
A selectable locker as the last post said is a good option. I run a detoit truetrac in my f150, and recommend that to anybody that runs on or off the road. It's awesome. The only time you spin just one tire is if it has NO load on it, like when it's off the ground. There are no clutches to wear out, totally gear driven. Read some of my posts about them. I go into alot of detail about this topic

you could always look at the Powertrax Lock-right, or the no spin locker. These both install into your existing differential carrier (they replace the spider gears), No disassembly and re-setup of the differential is necessary, and they're around $300. They basically give you a detroit locker. I know 3 guys that use them, and they work great.
