For Iphone 5: Lifeproof or Otterbox Armor?

I'm thinking of buying a waterproof case for my phone but I'm torn between lifeproof or otterbox. I'll be purchasing it before I hit the beach by the end of June and would like to know which case can go in deeper water.

Amazon's otterbox armor's on sale for $66 but Lifeproof is still $79. I'd like to know your thoughts & opinions on which is the better case for you in your experience.

Otterbox Armor, because it sounds more awesome.

The Otterbox is 100% safe for your phone i have one and it water proof shock proof its great for a iphone 5 i would recommend the otterbox defender for the iphone 5
