I didn't vote because, like you, I couldn't make up my mind...I love both styles, but as mentioned previously, with PH, you don't have to worry about vachetta at the bottom.
PH, the little gold chingaderas on the zipper make a cute sound when you walk....I have the Cabas and I like it too but if I had to do it over again, I'd do the PH
The cabas piano, IMO is more like a tote and the PH is more like a handbag. The bottom vachetta leather on the cabas is going to be a challenge, so I say go with PH, it's more modern looking and it got great balls, too!
