I do not own an Insolite Wallet, but I love my ZCW. My wallet of choice is the Zippy in all colors, especially the Multicolor! But since you don't like the accordion style I would suggest the ZCW. To be honest, even though it's smaller, the ZCW holds everything my Zippy's do! I was amazed.
The Insolite just looks so big. For one thing I don't carry a check book, so for me, there's just no need for such a large wallet.
I hope you can go and try them both. That's the very best way to get what you will love for sure!
