I would also choose the mini bumbag! I bought the nano Speedy last year and returned it … I know it is considered the more classic and popular bag, but it just didn’t do it for me. The quality on the one I received was very bad, and although it was cute, it just felt a bit basic to me.
On the other hand, I haven’t stopped using my mini bumbag since I got it this summer; it is just so versatile and fun and more unique IMHO. I think they probably hold about the same amount, but I find the mini bumbag is easier to get into and out of.
Personally, I would keep that one, especially because it’s still really hard to get in most places; I think the nano speedy will probably always be somewhat available/accessible, whereas the bumbag might not always be easy to find.
That being said … I am planning to buy the nano speedy in empreinte and possibly denim in the future
— I do like the bag in general, I just don’t personally love the monogram version. Good luck making your decision! 
I haven’t watched the video yet, but his post may be where she got her info from — not sure! 
she’s so adorable!! I was really worried about it having a wonky front pocket (I’ve seen so many with that!) but this one’s good. There are still a few areas that I wish were better aligned but I think the nature of this bag is that it’s going to show any imperfection no matter how tiny, so it is what it is. Love the microfiber lining. I think I’m going to use the chain from my DZP as a longer crossbody strap. Overall, I highly recommend it.
