I've only had the faucet installed for a few days, but I really like the pull out sprayer.  I replaced a very old faucet that was having some serious water pressure issues.  Removing the old faucet was the hardest part of the DIY; installing the Moen Marietta was quick and easy.  The matching soap dispenser is a great feature and I really like that I no longer have to keep the bottle of Dawn on the counter!
