Image stabilization; who has the best?

I don't know about you and EinsteinsGhost, but in my experience, there is almost always some kind of action when I use long focal lengths. Apart from the occasional moon shot, I can't remember using long focal lengths for still subjects.

And if there is action, I need some rather high shutter speed anyway, no matter how good the image stabilization is. I pretty much agree that 2 stops of stabilization help is all I can utilize without getting motion blur from subject movement.
