I have never been interested in the classic, but was intrigued by the reverse monogram. I just received mine and it has a couple of small issues, so I'm taking it back. I think if you are in the market for the PM style, the Reverse gets my vote, because it's different and no vachetta. I saw and tried on the Infrarouge but it was too bold for me. I would consider your overall bag collection and your wardrobe colors. I have a simple, minimalist style, so even the Reverse Monogram was too much for me personally.
At the end of the day, do as Olivia Pope would do and go with your gut.
