Limited-slip differentials are always good for street performance, and are quiet and easy to live with. I prefer a locker, due to the increased torque capacity, and the greater durability over the limited-slip. Although I am personally fond of plate-type limited-slip, the Auburn cone-type is very reliable. Later designs like the Torson, and the geared designs now making their way into the aftermarket, are supposed to be tougher than the "traditional" LS diffs.
