Which Of These 3 Cases Is Best? Why?

[BfA]

I'm looking at a case for my Telus Touch Pro. I purchased the Boxwave screen shield, so now need a case to protect the device itself. I've never bought one before so I'm not 100% sure what to look for when purchasing one. So i was hoping someone could give me some advice and let me know if any of these were good. Money's not really an issue as I'll be using it for a few years.

3 I'm choosing from:

Black Shield Protector Case for HTC Touch Pro (Sprint, Alltel)

Innocase Surface - Black
$30

Textured Black Phone Cover
$25

Right now I'd say I'm leaning towards the Innocase as it says it's only 1mm thick and I'd prefer something as thin as possible. Not sure if rubber makes a difference or not.

Also, I'm in Canada so not sure if shipping would have any issues with any of these.
