Both! With PHW, it looks more modern and fresh. And with GHW, it looks very 70's vintage-y (bright pattern tones). You really can't go wrong with either.
I have order a Vert Bengale in Epson DEF with GHW 32cm... I just think Gold makes it richer! In general the darker colors look better with gold and lighter colors look better with Silver (PHW). But by the end of the day t depends on you
