We went through this same decision, the Santa Fe is an awesome value for sure. We test drove one and found it rode nice and was as quiet as the Edge. In the end though we ordered a Edge AWD Limited, mainly because my last 2 vehicles have been Fords and I haven't had many problems with them. The Edge is made 30 miles from us here on Toronto, and we were worried about buying a new updated model year vehicle.
In the end we ended up getting an awesome deal on our Edge AWD LTD for less than the Santa Fe anyways. We ordered our Edge on March 5th, hopefully the wait isn't too much longer.
