As an operator vs "runner", the Sunset 3rd Rail single motor drive wins hands down for me. Dual motor drives in my experience, have jerky stops and starts, and generally are geared to run like slot cars. I have studiously avoided dual motor drives after some the first few I got.
I have not Knowledge of Santa Fe prototypes and models so I can't comment on the accuracy of the paint details. However, I have both the F7 and FP7 in PRR freight scheme (green) paint. They are both well done paint jobs in my opinion, and accurate. Also the details specific to PRR seem accurate to me - modified passenger pilots, lift rings, antennas come to mind. I would have preferred that the F7s have the rear tapered overhang, like the FP7s, but Pennsy had them both ways. That feature was probably removed because of damage lifting the units with the lift rings on rear.
