As the owner of (past and present) several cars so equipped, I submit that there is a vast difference between various types of LSD. A plate diff' with too much preload will make a car "squirrely" in slippery conditions and can make the car tend towards understeer on dry surfaces (unless provoked [img]/ubbthreads/images/graemlins/cool.gif[/img]). This can of course be "driven around".
A well set up plate diff' should behave fairly well but getting a compromise that works wet and dry can be difficult.
A Quaife or Torsen type diff' should be well behaved under most conditions.
I don't particularly like locked type diff's although they are very predictable.
Lockers, as in either open or locked depending on situation, are awful and should be avoided.
I quite like viscous coupled diff's for the road but they can't take much of a beating and destroy themselves fairly quickly.
The behaviours of the above diff's (and the rest) are completely different to each other. It's up to the owner/driver/designer/whoever to decide what characteristics they want, eg what does the diff' do on overun as opposed to under power.
I would never have an open diff' in a light high powered car.
