Zippy Coin Purse hands down. I LOVE mine and rarely use my zippy organizer any more. I can fit 8 credit cards plus there are 2 more slots I can put receipts etc. or 4 more credit cards, there is the center spot which I put my drivers license & spare house key, then I can fit all my $ and change as well. You cant fit anywhere close to that with the Ludlow (if I am thinking of the right one). You wont be disappointed with the Zippy.
