I have them both.
My alma bb in epic black color was dated 2012 when it just published.
and I got my buci since day one they issued this bag as well.
im not the person who baby bag, I use it a lot, I carry my alma bb for a nice differ, with strap, I carried it almost everywhere, use it just like my favorite mm ( is there still anyone using this bag just like me? lol)
and buci as well, I used a lot with back pocket, inside of buci I ordered a bag insert, and I always carry my long wallet, folded bag, key, and extra card holder ( always on back slot)
I have to say
alma bb is much more lady like, this bag suits more fancy dinner, date night out for sure, this bag still my number one in entire collection, I love it more then Hermes bolide.
buci I always carry it with longest length, I don't like under arm style so I never carry it that way.
if money allows, get them both, if its not, get alma first ( alma bb already exist over 10 years, alma this style already part of classic in LV collection.
