What's the best kind of phone case? (iphone 5s)?

I just got my iphone 5s and I have broken 2 iphone 4s and an ipad mini, I also managed to break an otterbox and a defender case. I've never tried a lifeproof case? Are those as good as they say they are? Do they actually work? What's the best kind of phone case? Preferably waterproof, and in colours other than black!

Wow, sounds like you have my kind of luck lol. But you broke an Otterbox defender? I think the only other option would be to try the lifeproof case because I think that's the only other well-known heavy duty phone case. Honestly, I work in retail and the best selling phone is the Otterbox series. You can always order different colors online.
