3.91 gears in a 2010 V6 auto car?

Having finally secured a SS diff for my heap for the purposes of limited slip hoonage, I'm looking at moving higher-up numerically to either a 3.45 or 3.91 gearset for my 3.27-geared, 2010 V6 auto car.

Given that I'm moving over from a Ford product that produced vibration nightmares that never went away by simply moving from a 3.27 gear to a 3.73, yes, the 3.91 gears sound like an awesome option for my turd, but will this car benefit from the 3.91's, or is there a problem with stock driveshaft vibration at freeway speeds, and I should stick with 3.45's?
