I have a set of marathon winters that I'd love to sell, specifically because they're horrible in snow. they're great on ice but as soon as you get wet snow more than about 2 inches deep, they wallow badly, and if you're on a road that's crowned much, every time you apply power to the rear wheel it will tend to slip sideways rapidly.
I had Nokian W106s before and I liked those better. In fact when I buy my next set of studded tires, I may go with Nokian W240s if I can fit them under my fenders. I have one W106 that's still pretty decent and last year I put that on the back wheel for most of the winter.
The Marathon Winters do have a lower rolling resistance. If you stick to bare pavement and ice, they're fine.
Seriously, I'll sell my set for 1/2 the new price if anyone wants them. I'll use the proceeds to buy one new Nokian.
