I think it comes down to personal preference and experience with winter tires. If you like the Conti, there is no reason not to go with them as I am sure they are a decent winter tire. I personally know a lot of people who swear by Blizzaks for winter tires.

The TireRack is a great source for reviews from people so make sure you take some time to see pros/cons that others have had. If you have any specific questions, it might be a good idea to just give Gary a call and talk to him about your options
