Princess Cut Experts Please

[Diamond_Newb]

So i have been looking for a bit and bouncing around from GOG, to Brian Gavin, James Allen, etc....But Whiteflash just seems to have the most princess cuts with AGS ratings which is most important to me for the cut. Anyway i am thinking of pulling the trigger on a set for a pair of studs for my wife. They will be set standard prongs but in platinium. Which would you choose?? The difference at the end of the day is $100 but ctw is a little higher one the first set...not sure if it is worth it or i shoud go with the F's
What would you do?? If you have a better suggestion outside of these two...i am open to suggestions!!
