Two new trucks are going to be so close these days that it really comes down to just the few things you like better.  Things like seat comfort, visibility, climate control/radio layout, etc.  Even how close the nearest dealer for service could factor in.  I had the same decision about a year ago and went with the Ram.  I love it but I'm sure I'd be loving the Ford now as well.
I found that just going to each dealership a couple times and looking/sitting in the trucks made my decision easier.  You can research over and over online but there's no substitute from being able the see and touch the truck.  Of course, it drives the salesmen crazy but that's what they are there for :)
