I have much larger curves and a lot of the scale length passenger cars but still find that my 18" cars produce more of a prototypical serpentine appearance as they wind around the layout's 0120 and 0144 curves. I like to reduce or eliminate the angles produced at the car ends.
This is a matter of personal preference. Curves can be creatively hidden so the overhang isn't as noticeable. Less than scale length cars will always look short. This is of course my preference and my opinion. I think we each need to decide where we are going to compromise.
