Xterra is most capable offroad for regular offroad purposes
Then comes Pathfinder, but with too much plastic its expensive to break bits and bobs in desert.
Then comes Armada, huge and heavy as boat not recommended for regular offroad due to its size and weight issue that will get you stranded on crest.
Last is Titan, as its even more heavier than Armada and hardly have offroad grunt to survive in Dubai desert.
You missed the best Nissan offroader: Patrol. Current one is too expensive to go offroad, but prior to 2010 model is the best ride for Desert in whole middle east region. People swear by it.
