On-road you'll get more clicking and popping with a lunch-box type locker, since they lack all the "soft locking" bits that a Detroit has. Off-road, the Detroit is stronger since it is a full case locker, while the lunch box lockers rely on the stock carrier (thus the cost savings). In a front axle, the lunch box lockers may work better since they tend to unlock easier and so make turning easier than a Detroit.

(it talks about the LockRite, but essentially the same thing).
