I have all 3 brands, but almost never carry my one LV unless I am going out in the rain. My one remaining Bal, a black Twiggy I do love how it looks, but hate to carry it as it has no structure so it lays flat when you set it down. I have several BV's and have to say this brand is superior in quality by far. You will carry BV for years. I don't think Bal would last for years, mine is only a couple of years old and looks it despite the fact that I have not carried it often. But if you are looking for a bag that shouts out the designer name, BV may not be what you want.
well that's the beauty of all BV bags. They are so elegant yet subtle. ONLY BV lovers would spot a BV I LOVE THAT!
