As a disclaimer: I have not used the bag you mentioned.
Having said that, I have used (from a professional as well as amateur perspective) pretty much every kind of bag and support system out there. The absolute best solution for amateurs (and, depending on the scope, professionals as well) is a sling.
I'm using the one described here:http://www.amateurnikon.com/2015/01/the-best-camera-bag-for-travel.html
And let me tell you, it is well worth the very modest investment.
