I have the Modal folio case from Best Buy. The most important thing for me was how sturdy the case was when in stand mode, since much of my iPad use is at my desk with the Apple Magic Bluetooth keyboard. When in stand mode with the cover folded into a triangle, the Modal case is super sturdy, and it doesn't fall over no matter how hard you tap the screen. What's interesting is that pictures on the Best Buy website show the case mostly in stand mode with the front cover flat on the desk -- this is another way you can use the case in stand mode, and while this mode allows more adjustment of the angle, it is not nearly as sturdy. I always use it in the other mode.
As for protection, this case is not going to protect very well in a drop since it basically only holds the iPad by the 4 corners. However, it will cover both the back and the screen when transporting the iPad, and the fit and cutouts are all perfect. I also like how the cover is reversible, meaning depending on how you fold it, you can adjust it so that the part of the cover that touches the desk when in stand mode is NOT the part that touches the screen when closed -- something that I really like.
I will also mention that this case does NOT have a magnet that causes the iPad to sleep/wake when opened and closed. However, it DOES have a magnet that holds the front cover in place when folded around the back of the iPad when using it so it does not flop around.
