I don't really understand what you mean by depth perception. It has a depth map, if that is what you mean. The kinect is a great piece of hardware because it has an rgb, ir, depth camera, and a built in IR light (though I suggest adding some IR leds if you're going the IR route). It is fairly cheap now, and there has been a lot of work done with it, but if you're using only the rgb camera, the only thing different is how much it distorts the image. All the cameras you will ever think about using basically have the same amount of distortion, so that shouldn't be a concern. If it is, then calibrate your camera:

But I'm going to say that it is a waste of time unless you are doing an camera pose calculation.

The kinect does have a subtle advantage over other cameras, like the axis: It draws attention to it. Little kids love seeing things they see everyday used in a way they never thought possible.
