I am really leery of the new Ford system that shuts the motor down when you stop. It may work fine, I dunno, but seems to me it would put a lot more wear and tear on the starter. Maybe I'm wrong.
The GM system doesn't shut the motor off, it shuts down a sequence of motor cylinders when you are out on the highway. I don't like it either, but there are ways to turn that system off. I don't know if the Ford system can be shut off or not.
Haven't heard what Ram or the Japs are doing to hit current CAFE fuel standards. I assume Ram is doing something like GM and Ford, not sure about the Japs.
