Which is better the Sealy Posturepedic Right Touch OR the Sleep Number / Select comfort? And why?

I have heard pros and cons on the sleep number ? select comfort beds and some say they are Extremely hot as they are made from plastic and with the foam seperator between sides in the King size bed they are not as comfortable as they are touted. Im really wanting to hear input from people who OWN or have owned them so i can get a real feel for whether i should or Shouldnt go that route.
