if your OEM M3 diff blew after 15000 miles then maybe it was driver error.

Torsen's don't have wear items other than gears. They'll only break if one of your drive wheels leaves the ground and you shock the assembly upon landing [i.e. keeping your foot in it]. Then again, doing that is just as much risk to axles, pigs, trans gears...everything else in the drivetrain. In your situation, the Torsen was the fuse.
Clutch-packs can be destroyed in minutes if they're ill-suited to the application...like the OEM clutch pack in the R56 MINI Cooper S in the example I gave above. They don't "blow", the discs simply slip and turn it into an open-diff.
