I am picking in between these four diamonds, I am looking for the best quality and best light performance. There is one from HPD that is a bit out of budget but with a bigger size and crafted by infinity cut, which I heard is considered the best when it comes to diamond cuts. Is it worth the extra money for the cut and size? Which one will you pick?

Does super ideal cut really make a visible difference when it comes to light performance comparing to an ideal or excellent cut? Are AGS cert better than GIA when searching for the best diamond?
