I too am torn between those two wallets so I'm glad you started this thread. I was leaning more towards the zippy and it seems that most people are confirming that for me.
I have the zippy so I voted for that, but essentially the two wallets are quite similar in terms of space and organization. The main difference IMO is that the zippy is quite "flat" whereas the pochette has a snap front so it has a bit more going on in the front. But the zippy is more secure and I liked that feature.
Yeah...I think the zippy is the way to go. With that said however, if you're kind of crazy and OC like me...the top part of the actual zipper (not the zipper pull) tends to fade and don't look as gold (especially on the top) probably because of the use and also the touching/rubbing. But it is a nice wallet. I just wish that they would use zippers that stayed gold forever.
I have the Zippy and love it. Since I bought it especially with travel in mind, the security of the zipper sealed the deal. My phone fits in it nicely. Here's a pic.
