I say the bumper case is the best. Its made by Apple so you know its top of the line and the fit is spot on ( how many cases can you say that about ) As for drop protection i also think that the bumper is a win because think about it how often will your phone drop flat on its face, most of the time it will hit the edges...
 
If. But then again, if you drop it on a cobblestone walk, gravel, or other uneven surface the bumper may not be guaranteed the win. For that reason I'd go full case -- Incipio here though I'm not a fan of the feather.

My thoughts exactly.
 
How often do you walk on cobblestone surfaces anyway unless its in your driveway etc...
