4x4 gives better grip because it distributes engine thrust between all wheels leaving more redundant tyre friction for cornering. With part time 4x4 there's a problem when driving in conditions where the road has patches of ice rather than totally icy conditions, you can't engage 4x4 because the non ice sections will wind up the transmission, but then you don't have the 4x4 safety benefit when you hit ice. If you want a 4x4 for winter safety then permanent 4x4 is the way to go.But, why would you need to?
