Ju-Ju-Be backpack diaper bag owners!

I can't decide between the Ju-Ju-Be BFF and the Be right back! I think they are both cute but I just dont know which will fit my needs better.

I have a 6 year old and a cloth diapered 2 months old baby. I would need something to fit wipes, 3-4 of her pocket/Ai1 diapers, extra change of clothes for 6 yrs old, extra shirt for myself, extra change of clothes for baby, blanket, snacks, and most importantly a structured carrier because I plan on wearing baby most of the time. Plus extra space for little things like my phone, wallet and keys. Please share your experience with either one of these diaper bags and what's in your diaper bag so I would have a better idea of the storage space. Thank you!😊
