I strongly disagree, Disc brakes adds a 2 factors of stopping power that you completely lose with drums.
Wet, come on guys, just the wet stopping power alone should speak volumes. zero with drums..

Next is the one that the hardcore guys figured out, backing down extreme obstacles, like potato salad hill MOAB. Rear disc brakes don't loose any stopping power in reverse.
Drums do, they have a primary/secondary shoe system that is designed to work going forward, the way they work going backwards is greatly reduced.

I run rear discs on my grocery getter XJ because they simply work better. I'm using the Ford SVO discs (like explorer) but the kit comes with a spacer to preload the axle shaft bearings. If you just install the explorer brakes, they are C clip style and don't use a spacer for preload. W/out the spacer the bearing will come unglued.
