Anyone have 3.73's with the ecoboost and 6 spd transmission?

I had to decide between 3.15 and 3.73. I chose the 3.73 because it will have better acceleration and better towing if and when I ever need it.
The decision would have been tougher to make if I was choosing between 3.31 or 3.55 vs 3.73, but at that point the decision probably wouldn't matter.
Didn't want to sell myself short with 3.15 so went with the 3.73's.
Just wondering if anyone has real world experience with the new expeditions with the 3.73 gears.

Well this just in;

My parents got a 2015 navigator two weeks ago and I got to drive it for the first time last night. It has the same engine and trans as the Expediton but the Navigator has 4.10's (axle code 41)
Maaaannnn did that thing drive smooth and zip around nicely!!! All the more confirmation to make me glad we went with the 3.73's in the expy over the 3.15's.

(this should probably be moved to the transmission and drive train thread)
