In a nutshell...
Viscous LSD work, but are much less effective as the heat up. They can wear out as previously mentioned.

Cusco...many others, are clutch pack type diffs, and are generally the best performing diffs. They are adjustable for performance, And they tend to be lighter (rotating mass...important). Their issue is that they will require maintenance over their lifetimes...being clutches.

Torsen style diffs (quaife) is a gear driven differential, a bit heavier than a clutch pack, but bulletproof. Put it in and never worry about it again. It's issue is that if you ever lose complete traction on one wheel (lift in the air, water, ice etc) it basically turns into an open diff until you get traction again.

I know the next question ; Why did nissan put in a VLSD in our car? Easy answer...want to guess which diff is the cheapest to produce?
