The shift logic of the two is also obviously different. It would be interesting to see how the 6.2 would do with different gearing such as 3.73 like the F150. As far as engine braking goes, I agree that the EB doesn't have much in the way of engine braking but with things like that, every bit counts and the fact that they presumably didn't use tow/haul on the way down flaws that test again.

I get a kick out of those here saying that if the 6.2 could be manually held near redline (!!) it would pull that hill no problem......who here wants to listen to that V8 at 6,000 rpm for MILES.....makes my teeth hurt just thinking about it.
This is one of the reasons that I moved from my 5.4 to the EB to tow our TT. I'd MUCH rather listen to the EB at 2,900 rpm doing the same work pulling a hill that the 5.4 was doing at (an unhappy) 4,000...........much less listening to that 6.2 at nearly 6,000 (!!).
They mentioned the difference, I believe it was 53.5" before the trailer and 51 inches after hooking up the trailer with only ~900 pounds of hitch weight. Pretty sad for a half ton.
I don't mind the sound of my 5.4 towing but I will agree, being quieter while towing is probably very nice.
