IMO its not fair to compare XDrive equipped vehicle to your average SUV or Truck. most of them rely on traction control to transfer power, anything that has mechanical diffs will be better. old school audi would be awesome in snow with manual locking center and rear diffs.
i had a chance to drive my frien'ds G35x in snow and i like that it has snow mode(makes 50-50 TQ split), feels more confident.
i see you also have 04 maxima, i used to have two 03 maximas, auto and manual, miss them both everyday.
