I'm rocking this bad boy (LUVVITT):

It's very grippy-rubbery all over, and doesn't add any bulk to the sides, but has fantastic corner drop protection. Not a pocket lint magnet either type of rubber, just grippy.

To be honest, I bought the Spigen cases and did a product review on this LUVVITT case. I really, really like the LUVVITT.

It's a grippy TPU and adds minimal bulk to the sides while giving awesome corner protection. It's not as gaudy as the Amazon pictures make it out to be. It's my daily driver.

I also have 2 S7 Edge Spigen clear cases if you want to guy one off me I paid $4 for it.
