Benefit of a worm drive is you don't need a drag brake to hill-hold - however, it can't freewheel at all, either, which can be a problem (perhaps when using a dig, which decouples drive from one of the axles) as well as a benefit.
MOAs don't need two batteries, though often you'll see two small packs, one on each axle, instead of a bigger one in the centre. They also don't need two escs - one can drive two brushed (but not brushless) motors - Novak are at the forefront of the top end crawler escs, but any brushed esc can do if it can cope with the modest amp draw of two high-wind, high-torque motors (usually in the 35T-75T range).
