I own all of these bag except for the Speedy nano (too small for even me LOL). Well, I did own the
Gucci Soho but gave it to my sis when I got the Gucci Marmont camera bag (very similar shape and color). I well tell you truthfully that the two bags that get the most use are Chloe Small Faye (though you do have to be careful with the suede flap, I treated my suede) and the Chloe Mini Marcie Saddlebag (very hardy. durable bag). My Faye is in Cloudy Blue and the Saddlebag is in tan. I find these year-round colors so will use for all seasons. I have the LV Pochette NM in Damier Azur and it only gets used spring/summer due to the color. My Balenciaga Hip is in a bright purple and use it every season except for winter. The Hip bag fits about same as LV Pochette NM. These two (not counting Nano Speedy) fit the least. The Chloe Faye Small and Gucci Disco fit the most. The Faye fits a bit less then the Disco bag but has much better organization inside the bag. The Disco is simply an open bag with one large compartment and a couple small pockets on the inside of the bag. It also has a linen lining, The Faye has three interior compartments and one smaller pocket on the inside. It also has a nice suede lining on the inside of the bag. I also had problems with my Gucci Soho flipping over and spilling the contents everywhere and the zip was a bit of a hassle (have to hold the bag on one end while pulling the tassel to get it to zip). The Mini Marcie Saddlebag doesn't fit as much as the Small Faye but definitely more then the LV Pochette NM and Balenciaga Hip bag. The LV Nano Speedy while cute fits hardly anything...my phone won't even fit. I tried and it sticks out the top of the bag. If it can't fit my phone, it is in automatic no-go for me. Also, I believe LV Pochette NM is being discontinued so it might be hard to find now. The LV site says 'call for availability' which doesn't bode well for getting your hands on the bag (new at least).
