To be fair, it is. Having gone from a 335d to a 530d.
Anyway, as for driving on winter tyres, it obviously doesn't make you into a driving god or anything. The back end of my 5 series still slapped out a couple times, at low speeds, but it does make a massive difference.
For example, the picture I showed above with the incline, I share that drive with 4 other houses. All with varying FWD motors, ranging from A1's to Mondeo's and the like. A couple years ago, my 335d was the ONLY one who could get out the drive, regardless of the run up. I didn't even need a run at it, and being the closest to the incline, that was impressive enough. Never mind the map for one million torques, and the 6AT box that was in it. I never got stuck one. My mate came round with his C-Class and stupidly came down there, and took a good 2 hours of running up and down the drive just to make it to the street (clearly he had actually just melted tracks down to the ground before he eventually got out). But he almost never made it out the street either as it too is a small incline.
That sort of traction is the reason I use winter tyres. But obviously they help massively on the road once I'm out the drive. The roads up here can't be ploughed often enough sometimes. As can be seen in my picture on post 7891. Little chance my 5 series would have been successful in getting anywhere without the winter tyres.
