The hippie and the sabrina are completely different bags so choosing between them shouldn't be too hard. Ha!
Just think about how you like to carry your bags. Generally people wear the sabrina as a satchel since most agree it looks better that way, but it can be worn on the shoulder if you need to use your hands. It's not a crossbody, so if that appeals to you, the hippie would be better.
I know that reading through this forum, it's very easy to get caught up in the popular bags, even it may not be the one for you. Take your time and think about how you want to use the bag. Then make your decision based on that and not based on what everybody else might like more.
