Best brands imo are:

iSkin
Incase
Speck

But if your going with some cheaper cases i would go with Incipio and not the ones you have above..
 
For me the Seidio Innocase II is the best case. It gives protection but allows u to access the whole iphone.
 
Has a lot to do with personal preference too...

I am currently using an Otterbox Commuter and I have been very happy with it.
Otterbox is a great company to deal with also.

Before that I was using a Speck Candyshell and I really liked that case a lot too.
