We'll it really depends on your personality and your lifestyle. If your always on the go and are always dressed up the the timi & Leslie dawn bags would be your best bet. But if you are pretty casual then go with the other one. I got the Jj cole bag. I love the size and its pretty plain with colors because I didn't want anything to bright. It works with my every day style. It doesn't look like a diaper bag and that's why I love it.
Lol. My mood is different everyday. Sometimes I'm dressy, others not so much. With the Timi & Leslie, I love the fact that it doesn't look like a dialer bag and it can be used as a purse, later. With the Ju Ju be, it has a high resale value. I plan to cloth diaper and I have a toddler so they would both work great, as far as space. Which jj Cole style do you have?
