At the end of the day low nose or high nose or something else. In a nose to tail impact, both have positive features and both can cause problems.

I did a silly experiment. I made two lego cars that were no more than a square block on wheels, we filmed them creashuing into each other basically flat surface to flat surface, in most if not all occasions one or both leapt into the air. To me this was a good illustration of the fact that no matter what you do - in a front to rear impact, one or both cars can be lifted off the ground in some way and no matter what you do this can't be completely mitigated against.
