As usual, Justin nailed it. They cost more. Both my 870s used for HD have them, but this is because these are used for hunting with slugs. A simple bead also works very well for most folks.
NOTHING is quite as fast as a plain bead, but my experience is a peep sight(That's a GR sight w/o a press agent)comes very close.
The key is to find out what works for you and use it all the time...
Remember, sporting shotguns are pointed, "Serious" shotguns are aimed.....
