I am in the same boat as the OP, but I own both a 14' Raptor and a 12' 3.5L Eco boost.
Personally I wish the Raptor had the Eco. I love the quite ride, the drone of the Raptor engine/exhaust gets old and I am seriously thinking about sound lining it. Also the Eco with a tune is impressive, haven't tuned the Raptor yet, but both trucks are basically stock. Driving around in the Eco with the windows down is definitely more of a pleasure than the Raptor, even with the windows up the Raptor is just loud...
For just get up and go off the start the Eco has it, even stock.
The other thing though is it seems far too many companies miss their release dates, so I don't think I am going to wait too much, do the simpler mods and hold off on the more expensive ones until more is firmed up with the 17'. I am liking the idea though of surround cameras, extra storage, auto tailgate locks, rear camera further up for less debris and the quiet yet powerful engine....hopefully Ford though
