Lone dissenter here--I strongly believe that you should keep the AB bag. I like it so much better than the Tano bags. I haven't seen these in person I'll admit, but the other two bags seem kind of "eh" to me, and the second one kind of looks like a kooba sienna knockoff IMO (sorry guys--please don't hate me I am really not trying to offend anyone). Anyway, I love the AB bag. JMO though.
