i def think the small bag is very useful to go out to bars and stuff. its always crowded and i dont want to keep hitting people with my bag. in addition i cant protect small bag easier from the smokers (my friend burned me with his cigg when i was in high school, and since then, i am paranoid when i am close to smokers).
but for everyday usage, big bags are better. fit everything from wallet to sncaks/water bottle.
