I use a sprayer a lot, and this one makes it very easy as a pull-out.  I especially value the sturdiness of the pull-out cord.  It is more durable than the "average" I've experienced.  The way it operates means you can easily return it back into the interior of the main faucet, and have a more streamlined appearance.  I am also looking forward to a spot resistant stainless surface!  Compared to its predecessor, the Moen is more durable and substantial.
