Have you rode in similar conditions with a hybrid/commuter bike with snow tires? How well does that fat bike handle in the snow by comparison?

The conditions you rode in were fairly ideal for Winter. I'm using a Trek 7.2 FX with Schwalbe Winter Marathon tires, it cuts through fresh snow easily enough, and it's amazing in ice. The problem I have is with >4" of snow, and tire ruts. My thin tires/wheels get bounced all over the place with dozens of tire ruts crisscrossing. That's where I see a fat bike doing a better job, or at least I hope so.
