Hi GG -
Has to be said, they're both great binoculars, and we're fortunate to be in a position to make comparisons! Economic priorities being what they are, i'm sure we'll get along fine with what we already have!
Whether it is the 7x magnification that improves the handling of CA i don't know - however, it seems to be the sole different factor in the range of Leicas i've tried. I still think Leica are the most stylish design, although the Noctovid seems to have departed from that a little.
As has been said many times, most designs are a combination of compromises and it is important to understand what your own priorities and 'red lines' are within this blend.
For me, i can forgive soft edges in order to get better depth of focus, but CA - that's my personal red line. Other threads have discussed whether perception of CA is greater or lesser according to the individual eye, and some seem not bothered by it all. I accept that it can be induced in almost any binocular if you really want to push it, but if it is there in normal viewing conditions, i'm afraid i have to pass on that set.
