A lot of folks in these comments are talking about AWD/4WD with all seasons being the equivalent of FWD with snow tires. This isn't the case. AWD/4WD will help you get going when a wheel or two are slipping but having all seasons won't help you when you need it the most - stopping.

Snow tires are made of softer rubber compounds that will stay pliable and grip better in lower temperatures. They also have more siping and water channels that allow for more mechanical grip with snow and ice that all season tires do not have.

Snow tires with AWD/4WD is the best option if you can swing it. If you can't, FWD with snow tires will be the better option.

Another thing to consider is some all terrain tires that are often found/installed on SUVs and trucks are 3 Mountain Snowflake rated. While not the same as being a true snow tire, they will often add significant grip in winter conditions for braking and turning.
