 I bought this XLT with the 3.5L ecoboost to replace a 2015 with the 2.7L with 63,000 miles on it.  I needed more towing capacity, and this truck delivers.  I never expected to get better highway mileage than the previous truck, but it consistently does that.  The front seats are much more comfortable than the 2015, the rear seats need some help in that department still.
