What is your choice for an 8.75 differential?

I really like my clutch type OEM Trac-loc.It has enough slip with the power off to not make trouble in the turns, yet under power it locks up and spins both 295s. To make a cone type Sure-Grip do that takes a lot of tuning.Rebuild parts are available for that Trac-loc. Sure-Grips can be rebuilt several times,but eventually they wear out. The Trac-loc can take more power into it.It has 4 spiders to share the load, and the cross-pins cannot oval out a hole cause there is none, just ramps. The SG may eventually fail when the cross-pin ovals out the case hole, or the spiders break, or the splines rip out.
If youre making big torque or are running slicks,the Trac-loc is the way to go. Just about everything else can run a SG.
