The main thing I see people having a hard time with is refusing to slow down, or not using some gear besides "D" with the overdrive still on. 4wd doesn't make you safe to drive 50mph on a snow covered road.
Having driven both here and up there, I will say that southern snow is usually a lot slicker and harder to drive in than that dry yankee cornmeal snow, too.
I'd much rather drive in wet snow,,,, especially with a 4x4,,,, dry snow compacts and is slicker,,,,
