I tried an Otterbox Defender on my iPhone 4 and hated it, ended up selling it. My 4S had a Speck Pixelskin that I got free from Apple and loved that one. My 5 currently has an Otterbox Commuter I've had on it all 2 years and love it, it's the right amount of protection while not being as unwieldly as the Defender. I'd like to try the Commuter or Symmetry on my iPHone 6 too, but right now I got that cheap Luvvitt case, still waiting on my iPhone 6 but the case is suprisingly thin just not every nice looking, may be a temp case we'll see.
