This really depends on how you "carry" you phone. Do you like it in your pocket, or on your belt?
I prefer mine in my pocket. I don't want to look like I'm trying to prove something and I don't like the feel of it hanging off of me. I purchased this
Incase. It works great, feels good to the touch, has good grip, easy to put in pocket, and gives you 100 percent functionality of your phone. Also, it has a cool design to give your phone some flavor.
There are a lot of options out there. Just have to decide what you're looking for first. All cases have their own distinct advantages.
