Really depends on what you like and are looking for in terms level of protection but I have a few. I initially bought the Otterbox Defender. It's normally what I get because I need a holster while working. I like the Defender a lot but it makes an already big phone much bigger. I then got the Apple leather case and the Seidio Surface case combo. I got the Seidio mainly for the holster as it works with the Apple case. I also got the Seidio Dilex Pro case combo. Again, I got the Seidio Dilex primarily for the holster as it works perfectly with my Magpul case. Bottom line, the Seidio cases are very nice but I use the Apple case when I want slim and the Magpul when I want added protection. The corresponding Seidio holsters mentioned above work great for these cases.
