Toddler Diaper Bag- Juju Be or Kiki Lu??

Now that my LO is a toddler I feel like messenger style diaper bag isn't cutting it anymore.  It is heaving when I am chasing after him and we are using the stroller less which means I am carrying it more.  So, I am leaning towards a stylish backpack diaper bag.  Right now I am struggling to decide between the Ju-Ju-Be BFF and the KiKi Lu.  Both are just under $200 so I don't want to pick the wrong one.  Has anyone had experience with either or both of these bags?  Thanks in advance!
