The Eaton TrueTrac is a better all-around design than the G2 Clutch-type. The TrueTrac has quieter operation, faster locking, and doesn't wear like a clutch-type LSD. Clutch-type LSDs will require periodic rebuilds to replace their clutches, as well as friction modifier to ensure proper operation, which the TrueTrac does not. That being said, there's nothing wrong with the G2 differential, and it will work fine for your application, but the TrueTrac is simply a superior design.
