Since they became available last fall, I've switched all my machines over to super bands. I've started changing out the post rubbers, too.
They change the game enough that I jokingly call them "cheater rubbers". I find that I achieve better accuracy and power using them. Having said that, the ball spins around in enough unpredictable ways with the super-grippy rubber that you'll often see drains due to weird ball behavior that traditional flipper rubber just won't cause.
They're pretty, consistent across colors (if that's important to you) and don't need to be cleaned as much. They're more expensive, sure - but I'm not sure they'll need to be replaced any time soon.
Superbands for me, please!
