From what I read- I am not a pro drifter- pros will use a fully locked diff or very high preload for drifting. You want the rear wheels turning together in a drift. So a torsen diff would be the perfect combo for street driving but still driftable.

That's why Subaru chose it over a clutch type, the Torsen is more suitable for road use. Subaru discussed this on launch and suggested the clutch type might become an option, but, they didn't sell enough cars to offer too many options packages in the end. The aftermarket supplies these needs.
Torsen operate locked up unless one wheel requires differentiating. They do not slip progressively from the perspective of the engine power input. They deliver full engine torque as delivered to both drive wheels until grip is lost at one tire at maximum torque bias. Then, generally speaking, both drive wheels will spin together unless grip level differs left to right.
