The eDiff can put you into a spin if you ride the speed curbing through a series of esses. Basically, it can cause a wheel which is momentarily in the air to land with the brake fully applied, which results in a nasty surprise.
A very experienced fellow BMW instructor nearly took his car into the wall at Calgary's Race City Speedway like that. The car was on R-compound tires (higher grip levels than street tires), which of course contributed somewhat, but the system is not flawless.
A proper Torsen LSD won't put you off track backwards with one locked wheel, nor will it see you wear out your rear brake pads faster than your fronts.
While a decent system, it's not by any means a replacement for a proper mechanical (clutch or geared) limited slip differential.
I also find that the eDiff is pretty useless in winter conditions.
