I have a cerises pochette and I love it! I take off the strap though so it looks more like a clutch and a little less like a mini handbag. I bought it because I loved it so I definitely use it and don't care what others think. I wouldn't carry it over the shoulder though, that really doesn't suit me, at all.
For me personally I would use it inside my bag but not outside. Out of the two options you've listed, I would suggest the wapity. After saying this, the choice is ultimately yours and what you are comfortable using.
