If i used pushrods I can mount the pickup point as far outboard as possible on both setups, maybe marginally further outboard on a wishbone setup, and using pushrods the bottom wishbone doesn't need to be as beefy, although with an off-roader we need it to be strong to cope with rocks.
Wishbone length is a real compromise as chassis and important things like an engine and ancillaries get in the way, and we still have the issue of CV angles due to short shafts
Road vs Off road is always a compromise, the only way to make something handle on road with minimal roll and still articulate off road is with something like active suspension, Land Rovers ACE or current pneumatic system or a Kinetic style system.
Live axles have worse ride on road due to the much, much greater unsprung weight, and this affects road holding too, and we have things like inherent shimmy to control, but it's the unsprung weight thing that helps off road.
