Regular pickup trucks are horrid in the in any slippery condition.That last little snow we got, a regular pickup truck got stuck going up an incline in front of the wife. There was a long line of traffic behind him including the wife. They got him moved off to the side, and my wife started to go. They told her you're not going to get up that incline. She says watch me, revs up the little Subaru, and off she goes. No muss, no fuss, no tire spin. Best money I've spent on a vehicle in decades.

4x4 trucks without slip differentials and with reasonable weight in the rear are damn good.
Jeep uses a few different 4x4 systems, some great (Wrangler, Cherokee) while some, at best, are OK (Compass).
Quattro from Audi is still the best for roads, but my sedan has all season tires, not snow tires. Subaru uses an asymmetrical AWD system that is very good on slippery conditions. On the other hand BMW uses a system called X drive that is particularly horrible in snow, wet, mud conditions. AWD is not the same as 4wd, some a excellent, some are not.
