It's a tradeoff. You can create geometry (ooh, one whole quad!) and then set it to absolute reference frame or use some other way to make it always face the camera. Drawing the image each frame using glDrawPixels can be a few orders of magnitude slower than a quad with a texture, as long as the texture does not change too often. Just to say there are lots of ways to skin a cat, and you can't choose the best one for your situation unless you know about them.
