On dry pavement, it's better with 2WD and better on the mileage as well.
Hope that helps a bit.

Gimpp:
Had several lengthy conversations with Nissan service personnel, and another reading of the manual. Pretty consistently, here is what I've learned:
1. Reasonably short trips on mostly dry pavement with intermittent icy patches no problem (10-20 miles) during winter 4H no real problem
2. Wouldn't want to take a long trip on dry pavement in 4H
3. As soon as the roads dry up between storms, switch to 2H
4. In 4H, stay under 55 mph to avoid heat build up and excessive wear on mechanical parts
5. At moderate speeds under #1 above, no material wear on mechanical parts. Expect greater wear on tires and lower mpg whenever in 4H
6. Essentially, 4H can be left in a "set it and forget it" during stormy periods and during the melt off until the roads become dry, as long as the speed is kept moderate.
Does this sound reasonable to you?
Thanks.
