Best iPad 2 Case?

[techairlines]

I'm looking for a good case for an iPad 2, preferably something that supports the new Sleep Mode through magnets, like the Smart Cover. I don't want the Smart Cover because I'm going to be traveling with this and the Smart Cover really doesn't provide much protection.

I'm deciding between these 3 (Amazon links):
CaseCrown: http://www.amazon.com/gp/product/B004R7A9NU/
Bear Motion: http://www.amazon.com/gp/product/B004Q7KTF4/
Acase: http://www.amazon.com/gp/product/B004UDH29K/

I'm about the order the CaseCrown one because the reviews are mostly 5 stars and the price is low. The only problem is that it apparently does not protect corners. Looking at the picture, the Bear Motion doesn't seem to either. Which would everyone here prefer?

And if you have an iPad 2 case, which one did you choose to get (doesn't have to be on my list above)?
