The G - Wagon is superior to the Defender in many ways and is the vehicle of choice for many serious explorers. However if the Defender was built to the same price it would have the advantage. A range rover is a fairer match. Drawbacks include steering wheel wrong side, enormous price tag, mercedes poor reliability and build quaility (though getting better again) too expensive to use as a work vehicle and hard to repair in the third world. Looks matter of taste as it is with all things and no real history and marque mystique.
