I have the SkipHop Pronto and LOVE it. I love it so much that it became my standard baby gift and everyone that I give it to loves it as well. I love that it stays closed even when I stuff it with way too many diapers and wipes. I also love the zippered pocket where I can put my keys, snack for DS, small toy, etc.
To be honest, ever since I bought the Pronto, I haven't used a diaper bag. The pronto suffices along with my regular handbag.
I've never used the BeChanged, so I can't compare the two, but I'm really happy with the Pronto.
