the actual Ridge is much better in terms of how easy it is to slide cards in and out, and adjusting the width when I want to.

I've had all kinds of wallets before this - money clips, Belroy, traditional three fold, leather clip style, etc...at this point I use the ridge as my every day wallet in my front pocket, and I have a large leather passport holder style wallet that holds the rest of my credit cards and I use if I travel out of the country (at least when I used to be able to do that.)
