eLocker with the standard TCS BLD is my opinion the best configuration... if you intend to actually go places where the locker is needed. Speaking for my Durango, I agree BLD is nicely implemented and does very well.
With TCS BLD being so good and standard in all models, I'm trying to understand why FCA added the option for Antispin. I think the answer is that it provides a smoother initial side-to-side torque transfer in low-speed situations. That is, from a stand-still, Antispin I think will engage the other wheel sooner and with less spin compared to BLD. That can be the difference between moving forward or moving sideways.
