To be honest mate for an allrounder for reasonable money 4x4 I'd probably go for a shogun or discovery, for an out and out shooting/hunting bus then the defender is the machine but hardly the best on road ... Out of the pickups navara/l200/hilux there all good reliable motors, I'd say more personal choice than anything...
For offroad / road ability and reliability I'd go for the shogun/landcruiser/discovery2/3....for something you just want to go anywhere get muddy, dirty, stinking, then hose it out and not bother about road noise and handling.......defender....
