I'm personally using this: Rugged Hybrid Kickstand Case for Nokia Lumia 1520 | eBay as I wanted something more on the rugged end. It completely eliminates the ability to comfortably put it in a pocket now but it also softens up those death spikes on the 4 corners of the phone.
i just ordered the Nillkin Ultra Slim case that Daniel did a review on recently. Couldn't pass up the $10 price for a good slim case.
This is probably the best fitting and feeling case I've ever own for any of my Lumias. Nillkin Ultra Slim. White on white.
