For my case I went with this Spigen case:

It has a need kickstand in it that has already proven useful. However, I'd prefer something that was more grippy and had a thinner profile. It adds a fair bit to the sides of the phone making it more difficult for one-hand operation.
To protect the screen, I got ghost armor from a mall vendor. I'm concerned about the ghost armor eventually peeling off due to the edge curves, but we'll see. The ghost armor also seems to be a bit of a problem for the Gear VR. I am a little distracted while using VR as I can see the ghost armor. I haven't tried the Gear VR without the ghost armor yet so I'm not certain what to compare it with.
