Otterbox (Defender) or Lifeproof?

I need a knew case for my Iphone 4 and I currently have an Otterbox Defender Case and I really like it. But I'm not sure which case/brand is better. I heard Lifeproof cases are awesome, but they are alittle more expensive than the otterboxes. Which should I get and why? What are the pros and cons of the Lifeproof cases and Otterbox cases?

I like Lifeproof cases~~

  • Should I get the Otterbox Defender series case for my iPhone 4? I really like the look of the defender series case, and I like all of the security it provides. So the big question: should I get it? Is it extremely bulky? Does the plastic casing part scratch the phone? Why do you like and dislike?

  • Otterbox Defender, Impact, or Commuter? I'm in need of an Otterbox for my iPhone 3gs. I don't know which to order… The Defender, the Impact, or the Commuter. What is your advice for the best one? Ordering online is hard since I can't hold them in my hand. My friend had the Defender whichi s pretty bulky, but I didn't know if the other two would give as good of protection. Thoughts?
  • Otterbox defender for iPhone 5? Does anyone have this case for their iPhone 5? I want to get it, but I don't like the idea of the built in screen protector. I heard it has air bubbles and makes the screen a tad bit blurry, but I wanted to know your opinion. Should I take it out and put a ZAGG on my iPhone instead?
