I have the black leather and black silicone and my partner has the clear case (all apple MagSafe ones).
SILICONE
Really nice case, just hate the silicone material, gets scuffed up very quickly, however, its better in some respects as it protects the metal band of the phone with the soft material around the edge, going to use this one when as my rough and ready case, when I am going to places that are dusty, dirty etc... as I feel it will protect my phone the best from dust and debris. Buttons are also nice.
LEATHER
This will be my primary daily driver, not material on the inside around the metal band, but its a much tighter fit than the silicone one. Plus it doesn’t mark easy at all and is quite durable. This is by far my favourite case. Buttons nice and clicky.
CLEAR
This is what I originally was planning on getting until I saw the ring on the back of it, personally, this is very un-apple to me. It picks up finger prints quite a bit, is a bit slippy and somehow feels bulkier than the other two types. Now had the ring on the back matches the colours of the iPhones I may have considered it. The buttons are also the hardest to press and the inside has no material protecting your phone from dirt and debris that may get between your phone and the case.
ADDITIONAL INFO
On my phone I have now removed the Belkin screen protector and replaced it with the ESR one, and I have to say it is FAR FAR better, edge to edge (apple cases go no where near the edges of the glass screen protector), no notch cut out, easy to apply and costs less than half the price of the Belkin one and you get a total of 3 screen protectors in the paclk. HIGHLY RECOMMEND... always used ESR in the past and decided to give Belkin a go this time thinking I would have a better quality protector... I guess it goes without saying you don’t always get what you pay for with screen protectors.
