Why would a clutch type be more beneficial than others? I understand a lot of people prefer the OS Geiken model.

Edit: From what I understand the main difference is that a clutch type works better when one wheel is off the ground. That would seem like a pretty rare circumstance on a rwd car on street tires with more or less open suspension modifications available. Is that the main concern for those recommending a clutch type? I don't like that clutch types may affect street driving and require service.

Edit 2: If the clutch type is the way to go, what are the thoughts on the Nismo 1.5 way?

Edit 3: apparently the lock in a clutch type has more tunability. The torsion types can be tuned as well but to a lesser degree. It also seems that the poor street ability comes on the higher ends of lock and that you can build diffs like the osg to have a more progressive street friendly lock transition. The biggest knock is service but if we are talking once a year, that doesn't seem so bad. What is the typical interval?
