Help with Antique Facets on Cushion! (Lots of photos)

[DRB]

Hi there,
I need to make an imminent decision on this Cushion Brilliant with some extra facets making it technically a modified brilliant as per its GIA. I feel the diamond is so unique I don't want to make the wrong decision.
My hesitation is on the contrast vertically. It turns on, but I'm wondering if it will bother me over time or if it's a good thing and adds a lot to the scintillation?
Thoughts?

I commented that I liked the stone in the other thread.
That bowtie going N-S is more stubborn than I expected.
Wait for other experts' comments.
