The exhaust brake has two modes on the Ram, but also feels different between normal and tow/haul mode where the transmission stays locked up longer. My EB on my Ford worked well when in tow/haul but there was no second setting or a separate on/off control on my 6.0 PSD with 5R110 (it was only engaged in T/H).
I also like the Ford mirrors better than Ram mirrors and never use the Ram mirrors rotated inboard since I do not save any width doing so and the field of vision is reduced.
My PSD was more responsive than my CTD when pulling off the line or accelerating on freeway ramps. The CTD does better at maintaining speed with less downshifts and accelerates better at cruising speed than my PSD.
The Ford controls are better for large fat fingered drivers or if you are wearing work gloves while driving. The Ram buttons are smaller and all feel the same under your finger tips so you spend more time identifying which button you are pressing. Ram has better instrumentation with vehicle vital signs - I had to buy a Scan Gauge II for my Ford, but found it was unneeded in the Ram.
The base cloth seats have different feel between Ford and Ram, but both are comfortable. The nod goes to Ford since the base seats include adjustable lumbar support. The center console in the Ram has convenient power, USB and line input jacks but is smaller than Ford's and does not allow you carry flat sheets of 8.5x11 paper or folders in the console.
