I wouldn't recommend a Wrangler for winter driving for the average Joe. While it will certainly go forward with the best of them in deep snow, the Wrangler has a habit of leading with the rear end! The short wheelbase, while great for off-road use, is very touchy in slippery conditions, especially in 2WD. Virtually any other Jeep would be a safer choice for winter, but I would lean toward a FWD/AWD setup for safety, such as a Subaru, RAV, etc. But if you're going to be driving in >12" of snow at low speeds, the Wrangler would be fine.
