The Destructor is a little larger than a standard pad, and a bit oversized for my keyboard tray as the edges hang off the sides. On the plus side, it does leave plenty of room for mouse movement. This is a Logitech iFeel that I've had for years and has Dotz pads installed on its feet. It slides very easily across the surface of the mat, almost too easily. I'm used to a soft cloth top pad and switching to a hard pad definitely takes some getting used to. For one, if your hands have a habit of getting sweaty while gaming then they tend to stick to the top of the pad. But on the plus side it is much easier to keep clean.
I spent about a week gaming on the Destructor and it works very well for that. Not once did I have an occurrence of the mouse mis tracking or jumping/sticking like I have had happen before with a soft pad. Also the larger size prevents having to lift and recenter the mouse as often, something that can save your life in a fast-paced FPS.
The rigid body is perfect if your mouse surface isn't quite flat, which could be a problem with a soft pad. And the case is handy I suppose if you are frequently on the go. But it's not like the Destructor is fragile, so the case seems a trifle overdone. Considering that the Destructor mat goes for around $40, half of which is easily the cost of the case, you'd think that would be an option. But I guess that's what the eXactMat is for. If you don't mind spending the extra cash for a high quality armored mouse pad case, the Destructor makes for an excellent gaming mat.
