There's no debate that lockers that connect with gears are more robust, and clutch type LSD/lockers are smoother but have higher risks of slippage. The responses I see are the potential failure points of clutch based and when gear lockers are preferred. That's not the intent of my posts.
I go back to my initial test: when the ELSD in the expedition is in locker mode, there was zero spin, not less spin or a faster transfer of power. True lockers immediately divides torque between the sides based on how much traction each side sees - there's no delay: it's physics. This is how my car reacted with the locker mode engaged - zero slip. Of course if I put the Expy in a much more harsh condition, the clutch can give way, but it acts as a true locker up until this point.
