I bought the emp pouch first and then when i decided to sell my wallet, i purchased the compact curieuse a month later. For me its more of what i take with me?! I use the emp pouch all the time bc it has my debit, cc, id, sb card in the pocket and any receipts or cash if any. In the zipper i keep my 2 work key passes as i don't take them out often. If im running an errand during my lunch break i just grab the pouch and go. I used the zcp like that for 2 years the same way, so now I take it out on the weekends to alt, this past weekend i used the de key cles.
The wallet however I keep in my bag to hold any extra cc, i keep checks in the billfold area. and theres plenty of room in the zipper and front pocket. thats pretty much how ive always used my wallets. I know most people take their wallet everywhere but it stays in my bag almost to organize/separate anything i 'may' need. Kinda strange i know lol i just like my most used stuff separate and i feel like its less obvious than grabbing my actual wallet just to run to the store without a bag. If im going out to dinner on the wknd i can always just take one or the other depending the bag.
