I’ve owned an edge 3.5L and a MKX 3.7L in the past. I’ve also owned a 2.0eb Fusion and Escape and we currently have a 2.0eb Nautilus. My F150 is a 3.5eb with 470 lb/ft. I’ve driven an Aviator 2.7eb.
The 2.0eb blows away the 3.5 and 3.7 in drivability due to the increased low end torque of the ecoboost turbos. It only runs out of steam above 5500 rpm but most don’t drive at WOT.
2.7 is definitely faster but most drivers would never notice or care about the extra power. They just don’t drive that way. So if you do drive that way and care, get the 2.7L. For everyone else the 2.0l is a great engine especially with the 8 speed.
