I want people to be able to notice that I have an iPhone 5S, and not a 5... Any recommendation for a really awesome bumper case?

If you are into minimalist design, I would suggest the SWORD 5 silver color. goes perfectly well with Space grey iphone 5S or black iphone 5. :)

Bumpers are great. Especially the newer ones compared to the original Apple one. They are thinner and don't scratch.

I like the Spigen Neo Hybrid EX Slim

It's also lighter than any other case since it has no back!

Lastly, it allows the back to breathe to prevent overheating the phone. Every iPhone design is meant for the back plate to be the heat dissipator. Heavy use or charging does heat up the phone.

The Spigen Neo Hybrid EX Slim is perfect. I purchased some new colors in the last 2 months and the occasional bumper slipping has disappeared. I think they tightened up the fit. Confirmed on two cases.
