My experiences:
The Neverfull comes with a pochette which is perfect as a wristlet.
Also, the bag is fairly large and can hold a lot of items but can also be cinched up to be smaller and less "tote" like.
For a SLG, the Jeanne wallet comes with a card holder and coin pouch that can be removed and used in other bags.
I actually own a neverfull but I purchased mine before it had that handy pouch.
