Lifeproof or Otterbox for iPhone?

What case does a better job protecting and deserves to be bought?

Otter box.

Otter box bought it makes your phone extremely fat

Simple. Otterbox is more protective but not waterproof. Lifeproof is not quite as protective but it is waterproof. Which would benefit your needs more?

Otter boxes are generally larger which is what is there turn off and with there newly released Armour Case it can be water proof but is still large.

I like Otterbox, I just bought a cheap Otterbox from iCase-Zone.
