Gatlinburg TN-WDW driving route?

[yoopermom]

We're actually coming from WI, but stopping for a week in Gatlinburg. Two trip routers send us straight down/south (relatively speaking) past Atlanta, while two others send us down along the Atlantic coast. Mileage is almost exactly the same. We're looking for speed, not sight seeing. Those of you who have driven down from TN-WDW, which do you suggest? Thanks!

Personally, I hate I-95 and would avoid it given the choice.

Also, Atlanta's traffic is pretty infamous, but I've driven through there quite a bit and never thought it was nearly as bad as some people say if you just stick to the interstates ... even during rush hour I never thought it was that bad ... if you avoid rush hour you have nothing to worry about.
