I'm a cover junkie so I always spent a lot of money getting covers until I finally get the one that I put it on and never look back. I understand your dilemma as I had the same, I always use Clear cases so it can show all the phone's beauty, but there is something with clear covers and Black phones that I don't like, it seems that clear cases looks the best with White, Silver, Gray and Gold, basically with every color but black, I don't like the contrast of colors when pairing them, the next best thing is the "Clear Covers" with the Smoked Black borders or complete.
So I bought a Generic Clear one with Bumpers side, it lasted 2 minutes on, hated it, then I got a CaseLogic one that was used for about a week until I got the 2 Tozo covers (Similar to the Peel case), one Blue (loved it) and one Mocha Black (Didn't look as expected) but these 2 covers doesn't protect other than from scratches, they are basically the thinnest and lightest covers available.

Then I got the Ringke Air Smoke Black, it looks good but like I mentioned above there is something with Clear Cover (even with Smoke Black tint) with Black phones that doesn't look good to me.

So I got a Ringke Fusion and these 2 Ringke Covers are the ones that I'm currently using and I'll keep using for a while, of the 2, the Fusion is the prettiest as I bought it jet Black just like the phone, and I like that it keeps the same look while it protects very well the phone.
Take a look at it to see if you like the Ringle Fusion jet Black just like I do.
