I love the Stella, love it and own it in several versions and use it a lot.
That said, in many ways the Venetics is THE iconic pockets-and-buckle Marc Jacobs bag. There is a reason it was one of the bags on the Lucky Magazine book covers (remember, there were 4 different covers I think?) - it defines the whole line for me in some ways.
Now, I have a Venetia (sap green, blue suede lining) and I rarely carry it, but if you are the type to carry that bag (you will know!) - it is really quite a bag.
If you are the type to carry a more "practical bag", then I can't think of a better bag than the Stella - chic, practical, durable, and just the best.
