Which iphone case is better? Lifeproof OR otterbox armor?

I want it to be water proof, drop/crush proof, dust, and cold/snow. I really want it to be thin-ish and water proof.
ALSO which one can go deeper in water and take a longer fall

Lifeproof

Well, i guess no case case is competely waterproof.
maybe a watherproof bag? Lol

How about a lifejacket for your iphone. With this secret weapon, your iphone can float on the water. Doesn't it miraculous?

You can look at Pelican cases, they are water tight, but don't take it under water, covered by a lifetime warranty, they come in many colors and sizes, drop Resistance and crushproof. Pelican cases are great but you can't go swimming with them, if you drop it in the lake, catch it before it floats away. You can look at Pelican cases at this website.

I'm biased, but I think definitely the LifeProof!

The Armor was meant to come out on June 25 but still isn't actually available yet, and I'm sure there will be some bugs to work out when it does come out.

LifeProof is drop-proof from 6 feet, can go 6 feet underwater. Armor says it can only go under water for 30 minutes before it fails. I've taken my LifeProof in the pool for hours at a time with no issues.
