If you need to be able to wear on the shoulder then I think GST is best. It's super durable in caviar leather and very practical with multiple compartments, key strap and zippered center. Also very good value right now for Chanel. Rumour has it the retail price of GST is going up soon.
If wearing on the shoulder isn't important to you, then garden party is lovely, and you know, well it's H!
