Here's my opinion-filled rating of open diffs through locker:

0 - Open Diff - no torque to wheel with traction, all torque to wheel with no traction. Great for going around corners and is easy on tire wear. Only helps when you are wheeling when both wheels have equal traction.

3 - BLD - better than open diff, but you do get some brake wear if you 'wheel much. The brakes are constantly being feathered on the slipping wheel. There's a slight delay in the BLD action so it doesn't engage around every corner. I have selectable lockers and have tried the BLD to get out of sticky situations. Certainly not as good as a limited slip but much better than open diffs.

4 - Limited Slip (AKA Trac-Lok) - much like the BLD except clutches in the diff engage to transfer torque to the slipping wheel. When new they work pretty good. As the clutches wear, it doesn't work as good. Can sometimes bind a little when going around corners and such, but not terribly bad. Most don't even notice - except your tires might wear a tad faster.

10 - Locker (Rubi, Detroit Locker, ARB, etc.) - when unlocked, all the advantages of an open diff. When locked, the axle is spooled - both wheels get equal torque no matter what.
