In my experience, my Sierra 1500 is a much better vehicle in snow. And snow is where the vast vast majority of my 4wd time is occurring.
Same reason I really like my current 2011 F250. Solid axels with a fair amount of frame clearance (all factory) and I keep good tires on it. Not nearly as nimble as a lot of the rigs mentioned here, but, so far that's not been an issue here in ND or anyplace I've hunted in MN, MT, WY, or AB. 7K # with a little running start will go through a LOT of snow.
