Looks like you want one with a built in screensaver.
I have used the Beetle Pro and really like it.
I use that if I go out and know I will be taking it in and out of my pocket alot.
The Armorbox looks very similar but also nice.
I think you will be happy with either one.
I've had the i-Blason since January 2015 and I have never been happier with a phone case. It has held up better than anything I've ever used. Fantastic for a $16 case.
I've had a Beetle Pro for a year and a half on my N6 and it has held up great and I am very rough on stuff. I just ordered the case you mentioned for the new N6 I just got, mainly got it for the flat back. my only gripe with the Beetle was it not setting flat. A couple times when it was on a wireless charger I'd get a notification and it would vibrate and move enough to stop charging.
