I did a fair amount of "internet research", which of course should be taken with a pinch of salt. Opinions varied as to what was better, with some dyno's showing non-X, some showing-X. Do you have definitive data on this?
I was thinking this morning of dyno'ing my car as-is, really to provide a baseline against which to judge the new engine when it arrives next year.

I totally appreciate the benefits of a balanced system.
