I own both. They are both great cars.

However, I find the Civic to be a safer and more dependable vehicle in difficult snow and ice conditions. Many folks (including myself) blame the traction control on the Prius which cannot be turned off in extreme slipery conditions. It is pretty humbling to get stuck in your own ice covered driveway, so much so that since then, the Prius stays home when the weather is acting up.

By the way, both vehicles absolutely need good Winter tires on all four wheels. The tires they come with are simply too unsafe to be used in snow and ice conditions.
