Speck Candy Shell:hard case so it can be difficult to get in and out...the rubber pieces on the edge are flexible but eventually they begin to wear out and even tear because u have to use a good amount of force to take the phone out of the case. Not to mention that it doesnt cover the chrome bevel completely...so u are taking a risk with this case
Switcheasy rebel capsule:alot of people rave about this case...but with the saggy bottom, it allows dirt and lint to get it in and possibly scratch the phone.
Incase Slider:I suspect this case is so popular because its available in the apple store and has a good assortment of colors.not to mention it looks pretty cool on the phone, but thats where the advantages end with this case...its a tight fitting case, so the constant removing and inserting of the phone can cause scratches. Im sure there are exceptions and maybe those people that say they dont have scratches from the incase just arent as anal as other people and arent looking close enough for scratches.
Finding a good case that will offer overall protection and looks is difficult. i know many people dont like silicone cases, but ive used many cases and so far the Switcheasy colors is great. Sure it collects some lint and dust but due to the type of silicone, its easy to wipe off. it doesnt collect as much dust as the iskin revo 2, so thats also a plus...and it also comes with port covers. Youre going to have to decide what to sacrifice, looks or protection? or perhaps somewhere in between, start looking at youtube videos of cases that catch your eye.
