I have owned a Escalade and the X5m is MUCH worse in mileage. Infact one of the worse vehicles I ever owned. But who buys one for mileage??

The DWS will get you through winter just fine. Don't worry about it. Unless you are driving through deep snow, you will be fine with DWS. I drove mine is snow with the summer RFT on it and it was OK. When I swapped to the DWS it was great.
