Baby Equipment-Rocker vs swing

So! I am a FTM and am trying to figure out what the buy for our little girl arriving in September. I have heard great things about the Rock and Play Sleepers and have also been told to get a traditional swing as well. We do not have a huge house to store bulky items when not being used so I am considering ordering a Cradle and Swing instead because it seems to be a combo of both. What have other moms found the most useful for giving baby options?
